Answer:

7

Step-by-step explanation:

7x + 68 = 2x + 103

Subtract 2x from each side

5x + 68 = 103

Subtract 68 from each side

5x = 35

divide 5 from 35 and you get X = 7

Two more questions , 15 points.
Mumz [18]

The formula that is useful for solving both of these problems is ...

(v_2)^2-(v_1)^2=2ad\qquad\text{a=acceleration, d=distance}\\\\ \text{where $v_1$ and $v_2$ are initial and final velocities}

9. Given v₁=15, a=9.8, d=10, find v₂.

... (v₂)² = 15² + 2·9.8·10

... v₂ = √421 ≈ 20.5 . . . . m/s

10. Given d=12 m when a=-9.8 m/s² and v₂=0, find d when a=0.17·(-9.8 m/s²).

The formula tells us that d=(v₁)²/(2a), which is to say that the distance is inversely proportional to the acceleration. If acceleration is 0.17 times that on earth, distance will be 1/0.17 ≈ 5.88 times that on earth.

(12 m)/0.17 ≈ 70.6 m

Harrison went out to buy coffee for his classmates. There are 23 students in his class, counting Harrison himself. Some wanted m
NemiM [27]

Step-by-step explanation:

Let's represent the number of mochas bought with the variable M, and the number of lattes bought with the variable L.

Since there are 23 students, the total number of mochas and lattes bought must be 23. This can be represented with the following equation:

M + L = 23

We can also set up another equation based on the total amount spent on the coffe:

4.30M + 3.50L = 87.70

If we rearrange the first equation, we can solve for M:

M = 23 - L

If we substitute this into the second equation, we can solve for L:

4.30(23 - L) + 3.50L = 87.70

98.9 - 4.3L + 3.5L = 87.7

98.9 - 0.8L = 87.7

0.8L = 11.2

L = 14

Subtituting this back into the original equation, we can solve for M:

M + L = 23

M + 14 = 23

M = 9

Therefore, 9 mochas and 14 lattes were bought.
