It will be "D" because 1/8 you need to make to be 1 so, you will multiply it by 8 and 8*4.5 will be 36.

The answer is D, because it takes four bricks to build 1/2 of wall, so 8 bricks for 1 ft. times 8 by 4 and get 32 for four feet. Add 4 more to get 4 1/2 feet.

At the local pet store, zebra fish cost $2.00 each and neon tetras cost $2.15 each. If Ernesto bought 15 fish for a total cost o
bezimeni [28]
So first create and define your variables:
Z = amount of zebra fish
N = amount of neon tetras

Now create your equations:
2z+2.15n=31.20
z+n=15
This is your system. There are multiple methods to use but in this problem I’ll use the substitution method by simplifying the bottom equation.
2z+2.15n=31.20
z=15-n
Now I’ll plug the bottom equation into the top one.
2(15-n)+2.15n=31.20
And just solve from here.
30-2n+2.15n=31.20
0.15n=1.20
n=8
So he bout 8 neon tetras, and 15-8= 7, so he bought 7 zebra fish

Angle C is inscribed in circle O. Line AB is a diameter of circle O. What is the measure of angle B? I can't get the picture but
WINSTONCH [101]

Answer:

Step-by-step explanation:

Since the inscribed angle theorem tells us that any inscribed angle will be exactly half the measure of the central angle that subtends its arc, it follows that all inscribed angles sharing that arc will be half the measure of the same central angle. Therefore, the inscribed angles must all be congruent.

What are the solution of the equation 2|×+7|-3=5​
marin [14]

Answer:

x = -3

Step-by-step explanation:

2(x + 7) - 3 = 5     (given)

2x + 14 - 3 = 5     (Distributive Property)

2x + 14 = 8           (Addition Property of Equality)

2x = -6                  (Subtraction Property of Equality)

x = -3                    (Division Property of Equality)
