X=15 since you subtract 1 from 27 then subtract 12 from 27 and you get 15
Answer:
174 CM²
Step-by-step explanation:
First we split up the triangular prism into shapes we can better understand (2 triangles, and 2 rectangles)
We solve the area of the triangles by using the formula to the area of a triangle (B·H÷2) 8·6÷2=24
There are 2 triangles therefore we get 2*24 which is 48 CM²
Now we calculate the area of the rectangles (7·10=70, 8·7=56)
Finally we add up all the numbers (70+56+48=174 CM²)
Therefore the surface area of the triangular prism is 174 CM², respectively.
ANSWER
D) (a + 1, b + m)
EXPLANATION
The given line passes through (a,b) and has slope m.
The equation is:

When x=a+1, we obtain

This


Therefore,(a + 1, b + m) must also lie on this line.
The correct answer is D.
Let $x be the amount of money which Kelci has raised. <span>Brianna has raised 3 times more money than kelci, then she has raised $3x. Totally both have aised $(x+3x)=$4x.
</span>
Since <span>together they have raised more than $300, then 4x>300,
</span>

.
Answer: the <span>inequality </span><span><span>

</span>can be used to determine the amount of money kelci has raised</span>
Answer:
896
Step-by-step explanation:
.There are 128 pens in 1 full box. Multiply 128 with 7 (as you are trying to find the total for 7 boxes).
128 x 7 = 896
There is a total of 896 pens in 7 box's
