N =D+7

0.10D +0.05(D+7) = 1.55

0.15D +0.35 = 1.55

0.15D=1.20

D=120/0.15 = 8

8x0.10 = 0.80

1.55-0.80= 0.75

8+7=15 * 0.05 = 0.75

8 dimes and 15 nickels

The area of the closet floor is 18 feet. If Saroya buys 32 tiles will she have enough to cover the floor?
kvasek [131]
No shel will not have enough tile.  If you don't know the dimensions of the actual tile how will you solve.  If you have a closet 18 square feet it could be 9 ' x 2 ' = 18 square feet. If the tiles were 12" x 6" you would need 36 tiles.  If the closet was 6' x 3' = 18 square feet you could have the tiles 12" x 6" = 36 tiles.  So you need to know the dimensions of the tile.

The diagram shows 15 identical circles, arranged as a rectangle, and a shaded triangle. The verticices of the triangle are at th
REY [17]
To find the area of the triangle, you will need to know the length of the base and there length of the height.

You can find both of these by using the circles that are given.

If the total length of the circles is 35 cm, then each circle has a length of 7 cm. If these are circles, then each circle has a height of 7 cm also.

A = 1/2 x b x h
1/2 x (4x7) x (2x7)
A = 196 square cm

Find the slope and the y-intercept of the line. 7x-2y = -10 simplest form​
____ [38]

Answer:

7/2 is the slope and 5 is the y-intercept

Step-by-step explanation:

Slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept.

7x-2y=-10

subtract 7x on both sides

-2y=-7x-10

divide by -2 on both sides

y=(7/2)x+5

7/2 is the slope and 5 is the y-intercept.
