Answer:
Adding them together. x = 3/2, y = 8
Step-by-step explanation:
Adding because we want to get rid of a variable. If we add, 2x + 6x = 8x, 1/2 * y + (-1/2 * y) = 0, and 7 + 5 = 12. Adding gets rid of the y variable.
By adding we get that 8x = 12 which gives us x = 12/8 = 3/2
Substituting this back into either equation will give us y = 8.

the answer is 12 yd if you are talking about the question mark.
Step-by-step explanation:
Well, if you split this figure into two rectangles, then the 16 yd length becomes 12 yd because the one congruent to it is 4 yd. Both sides are congruent so you'd get 12 yd.

A number cube is labeled 1 through 6. What is the probability of NOT
rolling a 2?
Answers
Answer:
Step-by-step explanation:
each of the 6 number has a 1/6 chance of being rolled
1 2 3 4 5 6
1/6 1/6 1/6 1/6 1/6 1/6
Every time the cube is rolled there is a 6/6 chance of any number comes up
1/6 + 1/6 + 1/6 + 1/6 + 1/6 + 1/6 = 6/6 or 1
What is the probability of NOT rolling a 2? Any other number
1 2 3 4 5 6
1/6 + 0 + 1/6 + 1/6 + 1/6 + 1/6 = 5/6 or 0.8333

two times the sum of a number and 18 is at least -21
Answers
Answer:
2x + 18 ≥ 21
x ≥ 2/3
Step-by-step explanation:
Let sum be X
2 times the sum means 2x
the sum of a number and 18 means x + 18
at least -21 means ≥ 21
put them together, and you get, 2x + 18 ≥ 21
If solving for x,
2x + 18 ≥ 21
2x ≥ 3
x ≥ 2/3

A. y =
B. y = x +6
C. y=-*-5
D. y = -x + 8
Answers
Answer:
y = -x - 2
Step-by-step explanation:
y = x + 2 {Compare with y = mx + c}
Slope = m1 = 1
Slope of the line S = m2 = -1/m1 = -1/1 = -1
(-6 , 4)
y -y1 = m (x -x1)
y - 4 = (-1)(x - [-6] )
y -4 = (-1)(x + 6)
y -4 = (-1)*x + (-1) *6
y - 4 = -x - 6
y = -x - 6 + 4
y = -x - 2

Choose Yes or No to tell whether the symbol will be reversed when the variable is isolated in each inequality. –10.5 < 3a b6 ≤ 7 –4.5c > 9 –215 ≤ –52d
Answers
Answer:
1). No, symbol won't be reversed
2.) No, symbol won't be reversed
3.) yes, symbol will be reversed
4.) No, symbol won't be reversed
Step-by-step explanation:
1.)
-10.5 < 3a
-10.5 /3 < 3a /3
-3.5 < 3 (No)
2.)
b/6 ≤ 7
Multiply both sides by 6
b/6 * 6 ≤ 7 * 6
b ≤ 42 (No)
3.)
-4.5c > 9
Dibide both sides by - 4.5
-4.5c / - 4.5 > 9/-4.5
c < 2 (yes)
4.)
–21/5 ≤ –5/2d
Multiply both sides by 2/5
-21/5 * 2/5 ≤ - 5/2d * 2/5
-21/2 ≤ - d
21/2 ≤ d (No)
