2x+y=7 solve for y. what is the answer?

Answer:

C

Step-by-step explanation:

Answer:

AB=2AM

3x-4=2(x+3)

3x-4=2x+6

3x-2x=4+6

x=10

So length AB 3x-4=3(10)-4

30-4=26

The length of AB is 26 units.

A line segment is denoted by two endpoints.

According to the given question M is the midpoint of segment AB.

Given, AM = x + 3 and AB = 3x - 4.

As AM is the midpoint if we take twice of AM that will be equal to AB.

∴ 2(AM) = AB

2(x+3) = 3x - 4.

2x + 6 = 3x - 4.

2x - 3x = -4 - 6.

-x = - 10.

x = 10.

So the length of the line segment AB will be (3x - 4) = 3(10) - 4 units.

= 30 - 4

= 26 units.

Answer

(-4,3)

Step-by-step explanation:

Answer:

Step-by-step explanation:

a(x) = 3x + 2

-3,0,5,6

a(-3) = 3*(-3) + 2

a(-3) = - 9 +2

a(-3) = - 7

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

a(0) = 3*0 + 2

a(0) = 2

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

a(5) = 3*5 + 2

a(5) = 15 + 2

a(5) = 17

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

a(6) = 3*6 + 2

a(6) = 18 + 2

a(6) = 20

Let the angle to be solved be x

Let the supplement/compliment by y

x+y=90 Complimentary angles add up to 90 degrees.

x+3y=180 Supplementary angles add up to 180 degrees, the other angle is thrice the other compliment.

Evaluating this as a system:

x+y=90 Isolate x:

x=90−y Input into the other equation:

(90−y)+3y=180 Combine like terms, isolate y and its coefficients:

2y=90 Isolate y

y=45 Input into the first equation:

x+45=90 Isolate x:

x=45degrees

Answer:

4 because you divide 3 and 15 by three which gives you 5 then divide 20 by that gives you 4

Answer:

Step-by-step explanation:

Given the expression 3x + 5/16 = 3/4 - 1/8x - 1/2

First we need to use the multiplication prope-rty before combining the like terms. The importance of this is to covent all fraction's to whole numbers.

Multiply through by 16

48x+5= 12-2x-8

Next is to collect the like terms

48x+2x = -8+12-5

50x = -1

Divide both sides by 50

50x/50 = -1/50

x = -1/50

The value used to multiply both sides is 16 and the value of x is -1/50

Answer:

The capacity of milk in 1 bottle is 2.99 liters

Step-by-step explanation:

Let us solve the question

∵ Sammy bought 15.3 liters of milk

∵ She poured the milk equally into 5 bottles

∵ There were 0.35 liters of milk leftover

→ At first, subtract the leftover from the quantity she bought to

   find the capacity of the five bottles

∴ The capacity of the 5 bottles = 15.3 - 0.35

∴ The capacity of the 5 bottles = 14.95 liters

→ To find the capacity of each bottle divide the total capacity by 5

∴ The capacity in one bottle = 14.95 ÷ 5

∴ The capacity in one bottle = 2.99 liters

∴ The capacity of milk in 1 bottle is 2.99 liters

Given:

Diego pays $4.50 for 3 pounds of bananas and 2 pounds of oranges.

One pound of oranges cost $0.75 more than one pound of bananas.

To find:

The equation which represents the situation, and what is the price per pound of each fruit.

Solution:

Let b represent the price per pound of bananas.

Cost of 3 pound of banana = $3b

One pound of oranges cost $0.75 more than one pound of bananas.

So, cost of one pound of oranges = $(b+0.75)

Cost of 2 pound of oranges = $2(b+0.75)

Diego pays $4.50 for 3 pounds of bananas and 2 pounds of oranges.

[tex]3b+2(b+0.75)=4.50[/tex]

Therefore, the required equation is [tex]3b+2(b+0.75)=4.50[/tex].

On solving the above equation, we get

[tex]3b+2b+1.50=4.50[/tex]

[tex]5b=4.50-1.50[/tex]

[tex]5b=3[/tex]

Divide both sides by 5.

[tex]b=\dfrac{3}{5}[/tex]

[tex]b=0.60[/tex]

Now,

[tex]b+0.75=0.60+0.75=1.35[/tex]

Therefore, the price of fruits are $0.60 per bananas, $1.35 per pound of oranges.

Hence, the correct option is C.
