Answer:
-2
Explanation:
-6 x -2 = 12
12 - 3 = 9
Answer:
p=-2
Step-by-step explanation:
Move the -3 to the other side by adding 3 on both sides:
-6p-3+3=9+3
The equation now looks like this:
-6p=12
Divide -6 on both sides:
-6p/-6=12/-6
The equation now looks like this:
p=-2 which is the answer

Solve the system of equations
-3x+2y=-6
5x-2y=18
Please help me
Answer:
the answer is (x,y) = (6,6)
Step-by-step explanation:
1) first solve the equation for 2y
you should've gotten:
2y = -6 + 3x
5x - 2y = 18
2) substitute the value of 2y into the equation
5x - 2y = 18
so, 5x -(-6 + 3x) = 18
3) now solve 5x -(-6 + 3x) = 18
4) from that solving that equation, u should've gotten x = 6
5) now plug in 6 for x in the other equation, solve for y
( • stands for multiplication if u didn't know, we use this in higher levels of math so multiplication symbols and x variables aren't confused)
5 • 6 - 2y = 18
6) after solving for y in the previous equation, u should've gotten y = 6
7) now we know that x = 6 and y = 6, however it is always important to check if ur answer is correct by plugging in the x value y values u ended up with into the original system of equations.
checking ur work would look something like this:
2(6) = -6 + 3(6)
5(6) - 2(6) = 18
hope this helps <3

The temperature at 3 a.m. was 3 1/2 degrees Fahrenheit. For the next 7 hours, the
change in temperature was 1 1/2 degrees per hour. Which statement correctly
interprets this situation? *
The equation 7(-1 1/2) = -10 1/2 means that the temperature at 10 am, was-10 1/2
degrees Fahrenheit.
The equation 7(-1 1/2) = -10 1/2 means that the temperature change from 3 a.m. to
10 a.m. was -10 1/2 degrees Fahrenheit.
The equation 7(-1 1/2) = 10 1/2 means that the temperature at 10 a.m. was 10 1/2
degrees Fahrenheit
The equation 7(-1 1/2) = 10 1/2 means that the temperature change from 3 a.m. to 10
a.m. was 10 1/2 degrees Fahrenheit.
My
Answer:
The equation 7(-1 1/2) = -10 1/2 means that the temperature change from 3 a.m. to 10 a.m. was -10 1/2 degrees
Step-by-step explanation:
Initially, the temperature was 3 1/2 degrees Fahrenheit at 3 a.m. From 3 a.m., the temperature change at 1 1/2 degrees per hour for the next 7 hours. This means that the temperature change in the next 7 hours is:
Temperature change = 7(-1 1/2) = -10 1/2
In the next 7 hours from 3 a.m. to 10 a.m., that is at 10 a.m. (3 a.m. + 7 hours), the temperature change was -10 1/2 degrees Fahrenheit.
Hence:
The equation 7(-1 1/2) = -10 1/2 means that the temperature change from 3 a.m. to 10 a.m. was -10 1/2 degrees

the average screen time for middle school students is 240 minutes per day. In 2020 students went into virtual learning and the average screen time is 70 percent longer. What is the total percent of screen time this year?
Answer:408=screen time
Step-by-step explanation:240+168 70%=168
make sure to like with the heart
Answer:
I believe 408 minutes a day
Step-by-step explanation:
So, I have my own method which is to divide the whole (in this case, 240) by 10 and multiply by whatever percent you have to multiply by and you add it to the whole.
ex.
240/10 = 24
24x7=168
240+168= 408
to do with 100s like 73% then divide the whole by 100 :)

find the area of a circle with a radius of 2cm
Answer:
12.566
12.6 (simplified to the tenths)
12.57(simplified to the hundredths)
Step-by-step explanation:
The diameter of a circle is always double of the radius
π is always ≈ 3.14
π * 2^2 = π * 4 ≈ 12.566

What is the total area of the figure below?
Answer:
141
Step-by-step explanation:
First find the area of the trapezoid
(16 + 10) * 9 / 2 = 117
Then find the area of the triangle
0.5 * b * 6 = 24
Add them both together
117 + 24 = 141

supppose v varies direcly as g, and v= 36 when g=4. Find v when g =11
Answer:
v = 99
Step-by-step explanation:
Given v varies directly as g then the equation relating them is
v = kg ← k is the constant of variation
To find k use the condition v = 36 when g = 4 , then
36 = 4k ( divide both sides by 4 )
9 = k
v = 9g ← equation of variation
When g = 11 , then
v = 9 × 11 = 99
If a triangle has 2 side lengths of 17 and 32, can
the length of the third side be 49?
Answer:
No
Step-by-step explanation:
In a triangle, the sum of each 2 sides must be greater than the third side.
17 + 32 ≠ >49
17 + 32 isn't greater than 49.
I hope this helps.

A family owns two cars. One car gets 35 miles per gallon and the other car gets 27 miles per gallon. In one week the family drove a total of 480 miles and used 16 gallons of gas. Can you determine the number of miles the family drove each car? Can you explain
Answer:
the 35 gallon used 6 gallons of gas while the 27 mile car used 10.
Step-by-step explanation:
35 x 6 = 210
27 x 10= 270
270 + 210 = 480
Find the product.
(x-3)(x+5)
Answer:
x2+5x-3x-15=x2+2x-15
Step-by-step explanation:
(x)(x)=x2,(x)(5)=5x
(-3)(x)=-3x,(-3)(5)=-15
Answer: X^2 + 8x -15
Step-by-step explanation:
Use the foil method.
First, outer, inner, last
Multiply the first numbers inside each parenthesis. X*X = x^2
Next multiply the outer number in each parenthesis. X*5 = 5x
Then multiply the inner numbers of the parenthesis. -3*x= 3x
Finally multiply the last numbers in the parenthesis. -3*5 = -15
Now add all of these together
X^2 + 5x + 3x + -15
Combine like terms
X^2 + 8x -15
X can be solved from here, however it does not seem that you are asked to solve for x
