Answer:
The equation is q + 10 = 20
The solution is q = 10
Step-by-step explanation:
"sum" means an addition.
"sum of q and 10" means "q + 10".
"is" means "="
That means you have the equation
q + 10 = 20
To solve the equation, subtract 10 from both sides.
q + 10 - 10 = 20 - 10
q = 10
Answer:
The equation is q + 10 = 20
The solution is q = 10
Answer:
X=-8
Step-by-step explanation:
18+x=10
-18 -18
x=-8
<span>In two similar triangles, like the one we see above, the ratio of their areas is the square of the ratio of their sides.
Based on the graph, we see that BD is 3 times larger than BA. This means that the area of DBE will be 3</span>² times larger, or 9 times larger, than the area of ABC.
Area of ABC = 3 square units
Area of DBE = 3 * 9 = 27 square units
Answer is A.
The perimeter of a rectangle is the sum of all its sides. As a formula, this is
P = w + w + l + l = 2w + 2l = 2(w + l),
where P is perimeter, w is the width, and l is length.
Let's apply this formula to your question and substitute given information, then solve for l.
P = 2(w + l)
10x + 6 = 2(3x - 3 + l).
10x + 6 = 6x - 6 + 2l
4x +12 = 2l
l = 2x + 6
