X/2-7=9 solve what “x” mean

Mathematics
1 answer:
Elden [556K]3 years ago
7 0

Answer:

x = 32

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

x /2  −7=9

1 /2 x + (−7) = 9

1 /2 x − 7 = 9

Step 2: Add 7 to both sides.

1 /2x − 7 + 7 = 9 + 7

1 /2 x = 16

Step 3: Multiply both sides by 2.

2*( 1 /2 x) = (2) * (16)

x = 32

Jimmy can run 3.5 miles in 20 minutes. how far can ne run in one hour and ten minutes?
prisoha [69]

Hello There!

Before we start, I am going to divide 3.5 by 2 because then we can multiply by 7 to see how far Jimmy can run in 70 minutes.

Jimmy can run 1.75 miles in 10 minutes.

To find out how many miles he can run in 70 minutes, we just multiply 1.75 by 7 and we get a product of 12.25

Jimmy Can Run 12.25 Miles In 70 Minutes

2. Write the slope-intercept form of the equation for each graph described. Line passing through (-5, 12) and parallel to the li
Nostrana [21]

Answer:   y = 2x+22

========================================================

Explanation:

The equation y = 2x+5 is in the form y = mx+b

m = 2 = slope

b = 5 = y intercept

Parallel lines have equal slopes, but different y intercepts. So the answer will be in the form y = 2x+c, where b and c are different numbers. Since b = 5, this means c must be some other number. If c = 5, then we'd have the exact same line.

Let's plug in (x,y) = (-5,12), along with the slope m = 2, and solve for c

y = mx+c

12 = 2(-5)+c

12 = -10+c

12+10 = c

22 = c

c = 22

Since m = 2 and c = 22, we go from y = mx+c to y = 2x+22

The equation of the parallel line is y = 2x+22

The graph is below.

What is 65% of 2,000,000?
dlinn [17]

Answer: 1,300,000

Step by step explanation:

Set up a proportion.

65 • 2,000,000 = 130,000,000

130,000,000 / 100 = 1,300,000

1,300,000 is 65% of 2,000,000
