Answer:
Step-by-step explanation:
if the angles form a linear pair, that means their sum=180
10x-63+8x=180
18x=180+63
x=243/18=13.5 choice c
Answer:
85%
Step-by-step explanation:
34/40 = 0.85
0.85 * 100 = 85
Answer: The cost of a small box is $4. The cost of a large box is $7.
Step-by-step explanation:
Let s = cost of a small box and L = cost of a large box
3s + 5L = 47
11s + 10L = 114
Multiply the top equation by -2 to combine with the second equation
-6s - 10L = -94
+11s +10L = 114
L cancels out, now solve for s
5s = 20
s = 4
Now, plug the value of s back into an equation to find the value of L
3(4) + 5L =47
12 + 5L = 47
5L = 35
L = 7
Answer:
17
Step-by-step explanation:
In this problem, you can use the Pythagorean Theorem to find the hypotenuse, which is x. The formula for the Pythagorean Theorem is: , where <em>a </em>and <em>b </em>are the two lengths of the triangle, and <em>c</em> is the hypotenuse (which is x).
<u>Steps:</u>
-We know the two sides already, which are 15 and 8, so we can substitute <em>a </em>and <em>b </em>into the equation: (the <em>c</em> is the same as x, just letting you know)
-Then, simplify the equation to get: (I replaced <em>c</em> with x just so you can understand better that we are trying to find x, the hypotenuse)
-Add the 225 and 64 to get:
-Find the square root of both sides to get x by itself:
-Evaluate the equation to get: which simplifies to
