4. If y = 5x – 3 and 3x - y = -1, what is the value of y?
A 2
B -1
C 7
D -8​

Answer:

150

Step-by-step explanation:

since 4 percent would have to be multiplied by 25 to get 100 you have to multiply 6 by 25. This comes out to 150. You can even check this by doing 150 times 0.04 which is 6 so we are correct!

Answer:

5 people

Step-by-step explanation:

1. I subtract 5.10 from 45 which gave me 39.90

2. I divided 39.90 by 7 to figure out how many people he could buy for

3. I had gotten 5.7 so I had to round

4 final answer is 5

Answer:

t = 9

Step-by-step explanation:

t/3 = 12 - 9

t = 3 * 3

t = 9

Answer:

t=9

Step-by-step explanation:

t/3+9=12

t/3+9-9=12-9

t/3= 3

3xt/3 = 3x3

t=9

Answer:

Step-by-step explanation:

2x+3y= 6     ========================>>>           2x +  3y = 6

x+y=4    =====   times both sides by 2  =====>>>    2x + 2y = 8

             ==== subtract these two equations ==>>  (2x - 2x) + (3y - 2y) = 6 - 8

                                                                                       0x     +      y       =   -2

        y = -2     so if  x + y = 4             plug in -2 where y was

                             x + (-2) = 4              add 2 to both sides

                                    x   =  6

(6,-2)

120

Step-by-step explanation:

If you multiply these numbers you will eventually find that they all have a common multiple of 120. 120 is also the least common multiple so therefore, the lcm is 120

Answer:

51 is 6% of 850

Step-by-step explanation:

0.06*850

Answer:

Let S = price of sweater

Let P = price of pants

S + P = 89.47 because that was the total spent

S = P - 8.53   because the sweater is 8.53 less than pants

Substitute P-8.53 in place of S in the

1st equation and solve for P

P - 8.53 + P = 89.47

2P - 8.53 = 89.47     add 8.53 to both sides

2P = 89.47 + 8.53

2P = 98.00  divide both sides by 2

P = 98.00/2

P = $49.00

S = P - 8.53

S = 49.00-8.53

S = $40.47

A sweater costs $40.47 and the pants cost $49.00

Hi

Answer: v = (6)(12)

Step-by-step explanation:

Answer:

Step-by-step explanation:

The factors are 9 and 27 are 1,3,9,27

With that, 9/27 is undoubtedly reducible to 1/3

Before now,we were told that when a number divides itself,the result is zero...now,⅜÷⅓ should give us 1 but 3/8×3/1 = 9/8 and 9/8≠1 hence,they aren't same!

Answer:

x = 25

Step-by-step explanation:

x + 25 + 2x - 10 + 90 = 180

Answer:

casey has the faster rate

Step-by-step explanation:

first multiply jessicas race distance and time by 2

30 * 2

= 60    

5 * 2

= 10

we did that so both jessicas time and caseys time was the same, making it easier to solve ( also by this point we already know who has the faster rate )

now we are going to divide both of their times and distances by 5

casey

10/5

= 2

45/5

= 9

jessica

10/5

= 2

60/5

12

the step is to divide their times/distances once again but this time by 2

casey

2/1

= 1

9/2

= 4.5

jessica

2/1

= 1

12/2

= 6

and our answer is 4.5 or casey !

4.5 > 6

hope this helps you! :)

Answer:

[tex]1 \frac{36}{84} [/tex]

simplified :

[tex]1 \frac{3}{7} [/tex]

Step-by-step explanation:

first, we turn them into improper fractions

[tex]3 \frac{ + 3}{ \times 4} \div 2 \frac{ + 5}{ \times 8} [/tex]

First, we multiply 3×4=12+3=15 the demoninator will remain the same.

2×8=16+5=21, denominator remains the same.

[tex] \frac{15}{4} \div \frac{21}{8} [/tex]

when it comes to division with fractions, you flip the right(direction)fraction then multiply.

[tex] \frac{15}{4} \times \frac{8}{21} [/tex]

15×8=120

4×21=84

[tex] \frac{120}{84} [/tex]

then turn in back into a mixed fraction.

[tex]1 \frac{36}{84} [/tex]

demoninator remains the same, how many times 84 goes into 120, which is once(whole number) and how many is left over (numberator)
