Let's use the variable (x) in this situation. 7 times x equals 1, or 7x = 1
first, find the opposite of 7x. We want to get x by itself. To find the opposite of 7x you would divide 7x by 7, and then do the same thing to the other side.
x = .14
.14 as a fraction would be 14/100

X+2/3=9/10 what does x equal
PtichkaEL [24]

Answer:

x = 7/30

Step-by-step explanation:

Identify the LCD; it is 30.  30 is the smallest number divisible by both 3 and 10.

Then we have:

(30/30)x + 20/30 = 27/30.

Clearing out the fractions, we get:

30x + 20 = 27, or 30x = 7

Dividing both sides of this result by 30 yields x = 7/30.

Skye made a deposit of $625 into an account that earns 4% simple interest for 6 years. How much did Skye earn in interest at the
tatuchka [14]

Answer:

She will earn 150$

Step-by-step explanation:

4% = 0.04

0.04 x $625 = 25

Now we divide 25 by the number of years, which is 6.

6 x 25 = 150$

Therefore, Skye earns 150$ from interest over the course of 6 years.

Divide and answer in simplest form: 1/3 divided by 5
disa [49]

Answer:

1/15

Step-by-step explanation:

1. You can divide 1/3 by 5 by changing the division symbol to its reciprocal, multiplication, and also divide by the reciprocal of the number after the symbol, 5. The reciprocal of 5 is 1/5.

2. Now you can do 1/3 multiplied by 1/5. Multiply the numerators by the denominators. The numerators are 1 and 1, so you multiply 1 by 1 which equals 1. Now you multiply the denominators, 3 and 5, which is equal to 15. If the numerator is now 1, and the denominator is 15, the new fraction is 1/15, getting you to your answer

Write the point-slope form of the line that passes through (5, 5) and is PARALLEL to a line with a slope of 1/4. Include all of
lesya692 [45]
Parallel lines will have the same slope

y - y1 = m(x - 1)
slope(m) = 1/4
(5,5)...x1 = 5 and y1 = 5
now we sub
y - 5 = 1/4(x - 5) <==== ur parallel line
==================
perpendiculr lines will have a negative reciprocal slope. To find the negative reciprocal, u flip the number and change the sign. So the negative reciprocal of 1/4 is -4....see how I flipped 1/4 and made it 4/1...then changed the sign making it -4/1 or just -4. That will be ur slope of the perpendicular line.

y - y1 = m(x - x1)
slope(m) = -4
(5,5)...x1 = 5 and y1 = 5
now we sub
y - 5 = -4(x - 5) <=== ur perpendicular line
