[12(x+3)-4]-2(x-1)+6]
Answers
10(x + 4)
Step-by-step explanation:
Simplify :
[12(x + 3) - 4] - 2(x - 1) + 6
= [12x + 36 - 4] - 2x + 2 + 6
= 12x - 2x + 36 - 4 + 2 + 6
= 10x + 32 + 8
= 10x + 40
= 10(x + 4)
Solve the simultaneous equations
5x - 4y = 19
x + 2y = 8
Answers
Answer:
x= 5 and y = 1.5
Step-by-step explanation:
5x -4y = 19
x + 2y = 8
let x = 8 - 2y...
5x - 4y = 19.......x = 8 -2y
5(8-2y) - 4y = 19
40 - 10y -4y= 19
40-14y = 19
-14y = 19-40
-14y = -21
y = 1.5
x = 8 - 2(1.5)
x = 8 - 3
x = 5
Thus, x is 5 and y is 1.5

Answers
Answer:
1. d 2. a 3. d 4. a 5. a
Step-by-step explanation:
For 1, d is negative because, if there an even number of negatives, the answer will be positive. a. would have been correct, but you multiply that one by 0. 0 is not negative, so the answer has to be d.
2. is -21. You can multiply 3 times seven then make it negative, or simply add -7 together 3 times.
3. is d because the two negatives cancel each other out. Even numbers of negatives cancel each other out. therefore, 17 times 6 is 102.
4. -120 is the answer because there are 3 negatives. That is an odd number, so we know our answer is negative. -5 times -3 is 15, and 15 times -8 is -120.
5. is a because -1 times 4 is -4, then -4 times -9 is 36. 36 times -3 is then -108.

m∠y = 50 (Due to A)
m∠x = 50 (Due to F)
Step-by-step explanation:
Due to corresponding angles,
x = y = 50
Also, another thing... You wrote 60 degrees as your answer for the first part, you did a slight miscalculation.
180 - 130 = 50
So the answer for the first part is 50 degrees. However, the reasoning is correct!

You have $6 to spend on lunch. The drinks cost $1.25 each and the salad
costs $0.20 per ounce. Write an equation in standard form that models
this situation.
1. 1.25 +.20x = 6
2. 1.25x + 20y = 6
3. 1.45x = 6
4. 1.25x + 6y = 20
Answers
Answer:
1. 1.25 + .20x = 6
Step-by-step explanation:
You will most likely just buy one drink and multiple ounces of salad with the 6 dollars you have to purchase a whole meal.
.20x, where x equals how many ounces you purchase
1.125 for the one drink
When set equal to 6 dollars you are able to find how much salad plus a drink you can purchase in total.
