How to solve -2/3 w+5=4

Answers

Answer 1

Answer: $- (2)/(3) w + 5 = 4$

Refine:

$5 - (2w)/(3) = 4$

Multiply both sides by 3 :

$3 * 5 -3* (2w)/(3) = 3*4$

Refine:

$15 - 2 w = 12$

Subtract 15 from both sides:

$15 - 2w - 15 = 12 - 15$

$- 2w = -3$

Divide both side by -2 :

$(-2w)/(-2) = (-3)/(-2)$

$w = (3)/(2)$

hope this helps!.

Determine which of these does NOT illustrate two quantities that combine to make 0. A) Jane collects 12 seashells and then loses 12. Eliminate B) Sharon lost 8 pounds and then gained 10 pounds. C) A business's profit if its income is equal to its expenses. D) Frank wins five dollars and pays back a $5 debt to a friend.

Answers

Answer:

Option B is the correct answer.

Step-by-step explanation:

A. Jane collects 12 seashells and then loses 12. This combines to become 0. as first Jane gets 12 shells and then loses same 12 totaling to 0.

B. Sharon lost 8 pounds and then gained 10 pounds. This does not combine to become 0. As Sharon lost 8 pounds then gained 10 making it a total of $10-8=2$ pounds.

C. A business's profit if its income is equal to its expenses. When the income and expense are equal, the profit is 0. Like you earned $100 and you spent $100, so you have basically 0.

D. Frank wins five dollars and pays back a $5 debt to a friend. This also combines to get 0. Frank gets $5 and then loses it by paying debt, so he is left with 0.

Therefore, option B is the only correct answer.

55.04 is 43% of what number

Answers

55.04 is 43 percent of a number. So first do 55.04 divided by 43 to find out 1 percent. This is 1.28. Now, all you need to do is move the decimal point two places to the right because it is times 100. The answer is 128.

55.04=43% of x
percent meas parts out of 100
43%=43/100=0.43

'of' means multiply

55.04=0.43 times x
diide both sides by 0.43
128=x

the number si 128

Step-by-step explanation:

a swimming pool had a list price of $575.25 and was on sale for 10% off.Sara had a coupon for an extra $75 off. What will her cost be before tax?

Answers

10%•575.25=57.525~57.53
575.25-(75+57.53)=$442.72

Answer:

First take 10% off of $575.25. 10% of $575.25 is $57.53, so 10% off would be $575.25-$57.53, which makes the price $517.72. Then, including the $75 coupon, reduces the price down to $442.72. Therefore, her price before tax is $442.72.

I REALLY NEED HELP PLZ!!!! PICTURE DOWN BELOW!the graph represents the last five years of computer hard drive production for Quality hard disks.
Part A
the variable T represents the time (in years). List the ordered pairs for t = 1 and t= 2
Part B
write an equation to represent the relationship between the time, t, and the number of hard disk produced ,p.

Answers

Part A:
To do this you have to find where t=1 and where 1=2. Then you have to go up the y axis (the vertical axis) until you hit a dot. For example, t=1, from t=1 you go up until you reach the dot which is located a 1,200. Then the ordered pair is (x [number of hard disks produced] ,y [time]) so it would be (1,1200)
Part B:
To do this you have to find a pattern between the x and the y coordinates. Easiest way is to divide the y by the x and see fi that works for all of the points. Example: (1,1200) 1200/1=1200 (2,2400) 2400/2=1200. Bingo! The relationship is multiple the x (t) coordinate by 1200. The equation would look like this: 1200t=p

Evaluate the function y = 17 – x. when x = –6

Answers

y=17-(-6) changes the equation to y=17+6 (since two negatives make a positive) and make the answer 23

Evaluate just means solve it. If x is -6, that just means put -6 in for x and solve.
y=17 - -6. Subtracting a negative is the same as adding a positive, so it's the same as y=17 + 6, which is y=23.
