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

Answer:

I believe the answer is the first one. definitely not the third or fourth. and it should only be exponented by t not 2t because then it'd be double what you should have.

Answer:

I dont know why the answers are the same thats how i got the answer solving them

Step-by-step explanation:

answer for 9x+3y=-15  

is

x=-5/3 -y/3

y= -5 - 3x

answer for -18x-6y=30

is

x=-5/3 - y/3

y= -5-3x

Answer:

it is the second one

Step-by-step explanation:

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

Answer:1.75

ep-by-step explanation:7 divided by 4=1.75

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

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.

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

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

Answer: 141

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 :)
