Answer:
B and E
Step-by-step explanation:
A. 8x = 2
8(4) = 2
32 = 2
B. 19 + x = 23
19 + 4 = 23
23 = 23
C. 40/x = 5
40/4 = 5
10 = 5
D. -3x = 12
-3(4) = 12
-12 = 12
E. x - x - x - x = -8
4 - 4 - 4 - 4 = -8
0 - 4 - 4 = -8
-4 - 4 = -8
-4 + (-4) = -8
-8 = -8
(a) Complementary angles
(b) Vertical angles
(c) Supplementary angles
<u>Explanation:</u>
Complementary angles are those two angles whose sum is 90 degrees.
Supplementary angles are those two angles whose sum is 180 degrees.
Vertical angles are the angles opposite each other when two lines cross.
(a)
Angles 1 and 5 are complementary angles
(b)
Angles 3 and 5 are vertical angles
(c)
Angles 3 and 4 are supplementary angles
To multiply a fraction, you simply multiply across the top and across the bottom.
-3 *-4 = 12
5 * 7 = 35
Final Answer: 12/35
The answer would be 28 feet, to get area you do length times width, 7 x 4 = 28
Answer:
y=−4
Step-by-step explanation:
Let's solve your equation step-by-step.
7y−4=−32
Step 1: Add 4 to both sides.
7y−4+4 =−32+4
7y =−28
Step 2: Divide both sides by 7.
7y/7 = −28/7
y=−4
