Your friend solved the
equation 4x + 12x - 6 = 4(4x + 7) and got x = 34.
What error did your friend make? What is the
correct solution?
4x + 12x - 6 = 4 (4x
4 (4x + 7
)
16x
16x + 28
- 166 6 166 16x + 28
x-6=28
x - 6+ 6 = 28 + 6
x = 34

Answers

Answer 1

Answer:

The equation is flawed.

Step-by-step explanation:

4x+12x-6=4(4x-7)

simplifying

16x-6=16x-28

-6 does not equal -28

The equation is flawed.

Answer 2

The required simplified solution of the given expression is given as x = 8.5.

What is simplification?

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
4x + 12x - 6 = 4(4x + 7)
16x - 6 = 12x + 28
16x - 12x = 28 + 6

4x = 34
x = 8.5

Thus, The required simplified solution of the given expression is given as x = 8.5.

[tex]\boxed{\pink{\sf \leadsto Yes \ there \ is \ a \ solution \ of \ the \ given \ inequality .}}[/tex]

Step-by-step explanation:

A inequality is given to us and we need to convert it into standard form and see whether if it has a solution . So let's solve the inequality.

The inequality given to us is :-

[tex]\bf\implies |2y + 3 | - 1 \leq 0 \\\\\bf\implies |2y+3|\leq 1 \\\\\bf\implies (|2y+3|)^2 \leq 1^2 \\\\\bf\implies (2y+3)^2 \leq 1 \\\\\bf\implies (2y)^2+3^2+2(2y)(3) \leq 1 \\\\\bf\implies 4y^2+9+12y - 1 \leq 0 \\\\\bf\implies 4y^2+12y+8 \leq 0 \\\\\bf\implies 4( y^2 + 3y + 2 ) \leq 0 \\\\\bf\implies y^2+3y +2 \leq 0 \:\:\bigg\lgroup \purple{\bf Standard \ form \ of \ inequality }\bigg\rgroup \\\\\bf\implies y^2y+2y+y+2 \leq 0 \\\\\bf\implies y(y+2)+1(y+2)\leq 0 \\\\\bf\implies ( y+2)(y+1)\leq 0 \\\\\bf\implies \boxed{\red{\bf y \leq (-2) , (-1) }}[/tex]

Let's plot a graph to see its interval . Graph attached in attachment .

Now we can see that the Interval notation of would be ,

[tex]\boxed{\boxed{\orange \tt \purple{\leadsto}y \in [-2,-1] }}[/tex]

Hence the standard form of inequality is +3y +2 0 and the Solution set of the inequality is [ -2 , -1 ] .

rob has 7.8 ounces of tuna salad. If she makes three sandwiches with an equal amount of tuna on each, how much tuna does she put on each one?

Answers

Answer:

2.6 tuna

Step-by-step explanation:

Amount of tuna salad rob has = 7.8ounces

Amount of sanndwiches made = 3sandwiches

If she had equal amount of tuna on each sandwiches

Amount of tuna in each = Total amount of tuna/Amount of sandwiches

Amount of tuna in each = 7.8/3

Amount of tuna in each  = 2.6 tuna

Hence she put 2.6 tuna in each sandwiches

X and Y are whole numbers.
X% Y finds the remainder after you divide X by Y.
For example, 7 % 3, means divide 7 by 3 and determine what is left over (7 divided by 3
equals 2 and the remainder is 1). So, 7% 3 equals 1.
Question
If X is a number. Which of the following will find the last digit of X?
For example, the last digit of 1327 is 7.
O A:X% 2
O
B:X%3
O C:X% 5
O D:X% 10
O EX% 100

Answers

Answer:

x%3

Step-by-step explanation:

The remainder of a division is the whole number, after the complete division. The expression that finds the last digit of 1327 is: [tex]X \% 10[/tex]

Given that:

[tex]X = 1327[/tex]

To do this, we simply test the given options.

[tex]X \%2 = 1327 \% 2[/tex]

When 1327 is divided by 2,

The result is 663, remainder 1

So, we have:

[tex]X \%2 = 1[/tex]

[tex]X \%3 = 1327 \% 3[/tex]

When 1327 is divided by 3

The result is 442, remainder 1

So, we have:

[tex]X \% 3 = 1[/tex]

[tex]X \% 5 = 1327 \% 5[/tex]

When 1327 is divided by 5

The result is 265, remainder 2

So, we have:

[tex]X \% 5 = 2[/tex]

[tex]X \% 10 = 1327 \% 10[/tex]

When 1327 is divided by 10

The result is 132, remainder 10

So, we have:

[tex]X \% 10 = 7[/tex]

[tex]X \% 100 = 1327 \% 100[/tex]

When 1327 is divided by 100,

The result is 13, remainder 27

So, we have:

[tex]X \% 100 = 27[/tex]

Hence, the expression that finds the last digit is: [tex]X \% 10[/tex]

Because the result is 7

(4−5y)−2(3.5y−8)

Answers

Answer:

-12y + 20

Step-by-step explanation:

First, you simplify each term:

apply the distributive property:

4 - 5y - 2 (3.5y) - 2 x -8

Multiply 3.5 by -2:

4 - 5y - 2 (3.5y) - 2 x -8

Multiply -2 by -8:

4 - 5y - 7y +16

Next, we simplify by adding terms:

Add 4 + 16:

-5y - 7y + 20

Subtract 7y from 5y:

-12y + 20

Hence the simplified form is -12y + 20

Jacks father drives to work in 30 min when driving at his usual speed. When traffic is bad, he drives 30mph slower and the trip takes one hour longer. How far is Jacks Fathers work from home in miles

Answers

Answer:

The distance of Jack's Father's work from home in miles is 45 miles.

Step-by-step explanation:

a) Data and Calculations:

Normal time taken by Jack's father to drive to work = 30 minutes

Time taken when traffic is bad = 1 hour longer

Speed when traffic is bad = 30 mph slower

Distance covered when traffic is bad, with time taken as 1 hour 30 minutes = time * speed = 1.5 * 30 = 45 miles

b) Jack's father normally drives at 90 mph (45 *2), this is why it normally takes him 30 minutes between his home and workplace when the traffic is not bad.  However, when traffic is bad, it takes him one hour longer and he drives at 30 mph slower.

Josiah and his children went into a grocery store and he bought $15 worth of peaches and mangos. Each peach costs $0.50 and each mango costs $1.50. He bought 2 more mangos than peaches. Graphically solve a system of equations in order to determine the number of peaches, x,x, and the number of mangos, y,y, that Josiah bought.

Answers

Step-by-step explanation:
p = peaches, m = mangos
1.75p + 1.50m = 22
m = p + 6
1.75p + 1.50(p + 6) = 22
1.75p + 1.50p + 9 = 22
1.75p + 1.50p = 22 - 9
3.25p = 13
p = 13 / 3.25
p = 4 <====== she bought 4 peaches
m = p + 6
m = 4 + 6
m = 10 <===== she bought 10 mangos
check...
1.75p + 1.50m = 22
1.75(4) + 1.50(10) = 22
7 + 15 = 22
22 = 22 (correct)

please help me!!!! Solve for x 5^x = 5^3 x 5^8 how was comuincation diffrent PLEASE HELP!!! My father always thought of fishing as a bonding ritual. His father had taught him fishing at a young age of six. The two of them would go off to a serene lake on a Sunday afternoon and return home empty-handed. They did not want to kill the fish as my father told me when I reached the age of incessant questioning. "That was not the point of fishing," he had explained. One morning, it was determined that I had taken enough swimming lessons to be able to rescue both my father and myself in the case of an emergency, and I was allowed to go fishing with my father. I wanted to pick out special clothes, but my father said I looked fine in my khakis and polo shirt. He did give me a beige visora bit too big for my faceto guard against the sun. That morning, he drove me in the sedan while my little brother and sister stayed home with Mom. Father spoke to me in his soothing baritone voice during the drive. "To think about nothing is important once in a while," he said. "You will know when you grow up." But I had thought fishing was my transition into adulthood. My hurried wish to grow up had pushed me into optimism at the age of eleven. As if my father could read my thoughts he said, "You are almost there, my boy." We took the scenic route to the lake. We passed the woods, the rolling hills, and approached the much talked about lake. There was sunlightthrown in silver sprinkles on the water. I helped my father unload the fishing rods and the cooler into the boat. We met the center of the river in silence. I suspended my fishing rod in the air feeling overwhelmed and satisfied by the beauty all around me. I had understood why my father did not bring the fish home.What type of language does the author use to create a peaceful mood?
