Find the value of each variable pls help for #10!!!

Answers

Answer 1

Remember that all triangles add up to 180. The triangle has congruent markings, therefore our equation will look like this:

11x-65+11x-65+29=180
Combine like terms.
22x-101=180
Add 101 to both sides.
22x = 281
Divide both sides by 22.
x = 12.77

Im struggling in math rn and i need help with this problem 3 1/4 = 1/2 + w

Answers

Answer:

w= 2 3/4

Step-by-step explanation:

First, we need to find what can equal w. So, we can subtract 1/2 form both sides, so one sides has just w and one side has just a number. 3 1/4-1/2= 2 3/4. So w= 2 3/4

Answer:

2 3/4

Step-by-step explanation:

3 1/4 = 1/2 + w

Transfer 1/2 to other side

3 1/4 - 1/2 = w

Solve

w = 2 3/4

Ben sells homemade cards at a craft fair. He wants to earn more than $50 at the fair. He sells his cards for $2 and he has already earned $36. How many cards foes he need to sell to reach his goal? Write and solve an inequality.

Answers

Answer:

He must sell 8 cards to reach the minimum goal.

Step-by-step explanation:

Giving the following information:

He wants to earn more than $50 at the fair.

He sells his cards for $2 and he has already earned $36.

First, we need to calculate the money required to reach the minimum goal:

51 - 36= $15

Now, we write the inequality:

2*x >15

x= number of cards sold.

x>15/2

x> 7.5

He must sell 8 cards to reach the minimum goal.

The dimensions of a rectangle are x+3 and x+4. The area of the rectangle is 72. Set up an equation that models this rectangle and solve in order to determine the value of x.

Answers

Answer: x = 5

Step-by-step explanation:

The area of a rectangle is the length times the width. Since the dimensions are given as functions of x, youre going to have to use FOIL to combine them, then set that answer equal to the given value of 72.

l*w = (x+3)*(x+4) = x^2 + 7x +12 = 72

Subtract 72 on both sides. There is a reason why we'll do this instead of subtracting 12. The quadratic formula will help us to solve for x.

x^2 + 7x - 60 = 0

Apply the quadratic formula

[tex]\frac{-7 (+/-)\sqrt{7^2-(4)*(1)*(-60} }{2*1} =\frac{-7(+/-)17}{2}[/tex]

We cant have a negative x value because that would result in negative dimensions and a negative area, which is impossible in this context. So you want to add the 17 instead of subtracting it.

x = 5 and x = -12

An alternate way is just factoring the trinomial to:

(x+12)(x-5) = 0

The trend line passes through (10,9) and (35,0). Write an equation for the trend line.

Answers

Answer: Solution :

Step 1 :

Make a scatter plot of Lily’s running data.

Step 2 :

To draw a trend line, use a straight edge to draw a line that has about the same number of points above and below it. Ignore any outliers.

Step 3 :

Find the slope of the trend line.

The line passes through points (2, 20) and (4.5, 45).

Use the slope formula.

m = (y2 - y1) / (x2 - x1)

Substitute x1, = 2, y1 = 20, x2 = 4, and y2 = 45.

m = (45 - 20) / (4.5 - 2)

m = 25 / 2.5

m = 10

Step 4 :

Find the y-intercept of the trend line.

Slope-intercept form equation of a line :

y = mx + b

Plug y = 20, m = 10 and x = 2.

20 = 10 · 2 + b

20 = 20 + b

Subtract 20 from both sides.

0 = b

Step 5 :

Use your slope and y-intercept values to write the equation.

Slope-intercept form equation of a line :

y = 10x + 0

So, the equation for the trend line is

y = 10x

It will be 9x + 1 = 12x + 20.

The answer you’ll put in the box is 1, because it doesn’t ask you to solve for x, just fill in the number.

Answer:

The blank in the equation is 1.

x = 7 and the vertical angles measure out to 64 degrees.

Step-by-step explanation:

When solving for x, you always want to keep the variables on one side. So you'll subtract 9x from both sides. That gives you 1=3x-20. Then you'll add 20 to both sides. This gives you 21=3x. After you'll divide by 3 on both sides. This gives you 7=x.

Now you'll plug in 7 for x. This gives you 12*7-20=9*7+1. First, you'll multiply which gives you 84-20=63+1. Add and you'll get 64 on both sides.

Price: $8.62 per 3 lb of strawberry
How much will it cost to buy 4.2 lb of strawberries? (Round to 2 decimal digits if necessary)

Answers

9514 1404 393

Answer:

$12.07

Step-by-step explanation:

The cost is proportional to the weight, so we have ...

dollars/pounds = c/4.2 = 8.62/3

Multiplying by 4.2 gives ...

c = 4.2×8.62/3 = 12.068

The cost of 4.2 pounds of strawberries is $12.07.
