Answer:
x = 2
Step-by-step explanation:
Given
4x - 3 = - 9 + 7x ( subtract 7x from both sides )
- 3x - 3 = - 9 ( add 3 to both sides )
- 3x = - 6 ( divide both sides by - 3 )
x = 2
The answer is b because it goes down .89 every time
his allowance is $14
to find this you:
11-4=7
7*2= 14
The 11 is what he had the four is what he was given extra and the multiplied by two is because he spent half of his money at the candy store
BO is double that of DO. In other words, BO is two times longer than DO. The answer is choice B
For example, if DO were 3 units long, then BO would be 6 units long (2*3 = 6). This works because the triangles DCO and BAO are similar triangles. The corresponding sides are in the same ratio or proportion to one another. The larger triangle (BAO) has sides that are twice as long as the smaller triangle's (DCO) corresponding sides.
Side note: we can prove the triangles to be similar using the AA (angle angle) similarity theorem. The first pair of angles are the vertical angles DOC and BOA which are congruent to each other.The second pair is CDB and ABD which are congruent by the alternate interior angle theorem.

Answer:
The volume of the rectangular prism is 24yd³
Step-by-step explanation:
We need to think of the hole as a rectangular base prism
To calculate the volume of a rectangular prism we have to use the following formula:
v = volume
w = width
l = length
h = height
v = w * h * l
we replace the values that we know
v = 2yd * 3yd * 4ft
v = 24yd³
The volume of the rectangular prism is 24yd³
