−9x−6y=15
9x−10y=145
​
y=
x=

Answers

Answer 1

Answer:

Step-by-step explanation:

Adding the two equations together gives you

9x-10y-9x-6y=145+15

-16y=160

y=-10, using this value in 9x-10y=145 gives you

9x-10(-10)=145

9x+100=145

9x=45

x=5

So y=-10 and x=5

Answer 5,824

Step by step explanation:

You want to buy a new car. You can afford payments of $300 per month and can borrow the money at an interest rate of 5.2% compounded monthly for 5 years.

Answers

Answer:

$367.17

Step-by-step explanation:

we are find the cost of the car after 5 years

Using the compound interest formula;

A = P(1+r/n)^nt

Given

Principal P = $300

rate r = 5.2% = 0.052

Time t = 5years

Time of compounding n = 1/12 (monthly)

Substitute into the formula

A = 300(1+0.052(12))^5(1/12)

A = 300(1+0.624)^0.4167

A = 300(1.624)^0.4167

A = 300(1.2239)

A = 367.17

hence the amount of the car after 5years is $367.17

Gabriel has 15 ⅝ pounds of clay. He will use 7/10 pound to make each bowl. After making 8 bowls, Gabriel wonders how many more bowls he can make. How many more bowls can how make?

Answers

Answer:

14

Step-by-step explanation:

The total amount of bowls he can make given the pounds of clay and the pound needed to make a bowl = [tex]15\frac{5}{8}[/tex] ÷ [tex]\frac{7}{10}[/tex]

= [tex]\frac{125}{8}[/tex] ÷ [tex]\frac{7}{10}[/tex]

= [tex]\frac{125}{8}[/tex] ×[tex]\frac{10}{7}[/tex] = 22.32

Number of bowls he can more more = total amount of bowls that can be made - number of bowls already made

22.32 - 8 = 14.32 bowls

Rounding off to the nearest whole number gives 14

How do you find the circumference of a circle? Please include an example if you’d like.

Answers

Answer:

Step-by-step explanation:

Plug the given value of the diameter into the formula and solve.[2]

Example problem: You have a circle tub with a diameter of 8 feet, and you want to build a white fence that creates a 6-foot wide space around the tub. To find the circumference of the fence that has to be created, you should first find the diameter of the tub and the fence which will be 8 feet + 6 feet + 6 feet, which will account for the entire diameter of the tub and fence. The diameter is 8 + 6 + 6, or 20 feet. Now plug it into the formula, plug π into your calculator for its numerical value, and solve for the circumference:

C = πd

C = π x 20

C = 62.8 feet

Jisoo drank 3/8 of a quart of chocolate milk, and his friend Andrew drank 2/7 of the same quart. How much did they drink altogether?

Answers

Answer:

37/56

Step-by-step explanation:

If Jisoo drank 3/8 of a quart of chocolate milk, and his friend Andrew drank 2/7 of the same quart, the amount they drank altogether will be the sum of the amount they drank individually

Total = 3/8 + 2/7

Find the LCM

Total = 3(7)+8(2)/56

Total = (21+16)/56

Total = 37/56

Hence they drank 37/56 of the quartz altogether
