Answer 1

Answer:

Step-by-step explanation:

The total charge ("total" is a clue word!) is the standard charge plus the insurance charge.

[tex]C=S+I\\C=(0.4M+17.75)+(0.15M+4.90)\\C=0.55M+22.65[/tex]

That last step comes from combining like terms (put the M's together and the "just numbers" together).

Subtracting a negative is like adding

x + (3) ≥7

Subtract 3 from each side

x +3 −3 ≥7-3

x ≥4

X must be greater than or equal to 4

Answers

Answer:

171 m

Step-by-step explanation:

Okay, so we have to find the area of all the shapes that make up the prism:

I'm going to start with the side rectangles:

5 x 7 = 35

There's 2 of them so:

35 x 2 = 70

Now let's go onto the side triangles:

4 x 6 = 24 (normally it would then be ÷ 2, but because there's 2 triangles, you don't have to do that)

Then we do the bottom rectangle:

6 x 7 = 42

So, adding them all together:

35 + 70 + 24 + 42 = 171

So the surface area of the prism is 171 m

hope this is right:)

Ciara brought $240 to spend on gifts for her family. she found 8 identical statues at the gift shop. she had $72 leftover. how much did each statue cost?(please write an equation for the answer like 2 step equation)

Answers

Answer:

$21 each

Step-by-step explanation:

Since she had $72 left that means that she spent $168 so then you divide that by the 8 identical statues.

$240 - $72 = $168

$168/8 = $21

Answer:

$21

Step-by-step explanation:

Price of each statue = x

Price of 8 statues = 8x

Price of 8 statues plus money left over = 8x + 72

Original amount of money = 240

Equation:

8x + 72 = 240

Subtract 72 from both sides.

8x = 168

Divide both sides by 8.

x = 21

Find the surface area of the prism.

The surface area is_______
square meters.

Answers

total surface area is: 416 m^2

740 square meters

First you do 16 times 10 for the base(the square on the bottom), this equals 160.
Then you do 17 times 10 for sides. We have two of these so just add 170 plus 170 which equals 340.
Next use the formula A=bh/2 for the triangle. A=16(15)/2 this equals 240 but since we have two triangles then we don’t have to divide it.
Then add all of your numbers which are 240+160+340 and you get 740.

I hope this makes sense
