solve the equation by combining like terms: 3x-5+12-2x=12

Answers

Answer 1

Answer:

482

Step-by-step explanation:

3x-5=178+12=82-22x=482

Answer 2
3x-5+12-2x=12
X+7=12 (by combining like terms you have your X’s and your regular numbers. So in this equation we have 3x and -2x as like terms and -5 and 12 as like terms. We combine them to simplify the equation. So by combing 3x and -2x, 3+(-2x), we get 1x or just x. Then we combine -5 and 12, -5+12=7).
X+7=12
-7 -7
X=5
Good luck and I hope this helps!

Answer:

x = 19 degrees

Step-by-step explanation:

180 - 114 = 66

Other triangle angle is 114 degrees

114 + 47 = 161

180 - 161 = 19

x = 19 degrees

Joanna is driving 185 miles to visit her family. She drives 68 miles in the morning, stops for lunch, and then drives the rest of the distance. How many miles did she drive after lunch?

Use the variable m to represent the number of miles she drove after lunch.

Which equation represents this situation and its solution?


m + 68 = 185; m = 117

68m = 185; m = 17

m + 185 = 68; m = 117

185m = 68; m = 17

Answers

Answer:

The equation represents this situation and its solution are m + 68 = 185; m = 117 ⇒ A

Step-by-step explanation:

Let us solve the question

∵ Joanna is driving 185 miles to visit her family

∴ The total distance she is driving = 185 miles

∵ She drives 68 miles in the morning

d[tex]_{M}[/tex] = 68 miles

∵ She stops for lunch and then drives the rest of the distance

∵ m represents the number of miles she drove after lunch

d[tex]_{L}[/tex] = m miles

∵ d[tex]_{L}[/tex] + d[tex]_{M}[/tex]  = the total distance she is driving

m + 68 = the total distance she is driving

∵ The total distance she is driving = 185 miles

m + 68 = 185

The equation represents this situation is m + 68 = 185

→ To solve the equation subtract 68 from both sides

∵ 68 - 68 + m = 185 - 68

m = 117 miles

The solution is m = 117

Wwhich expression uses the associative property to make it easier to evaluate 8(1/2x1/3)?
A.8/3(2x33)
B.(8x1/2)1/3.
C.8(1/3x1/2)
D.(8x1/3)1/2​

Answers

The correct answer would be B. (8×1/2)1/3.

Step-by-step explanation:

8 * [(1/2) * (1/3)]

= [8 * (1/2)] * (1/3)

= 4 * (1/3)

= 4/3.

The answer is B because it is easier to calculate 8 * (1/2), which is dividing 8 by 2 to get 4.

Step-by-step explanation:

list the integers that satisfy both these inequalities, 2x+9 <-12

Subtract 9 from  both sides;

2x +9 - 9 < -12-9

2x < -21

x < -21/2

x < -10.5

Hence all the integers are values of x less than 10.5
