Answer:

y=33

Step-by-step explanation:

we have

y = 6x + 9

Remember that

To predict a value for y, when x = 4

substitute the value of x in the equation

so

y= 6(4) + 9=24+9=33

Answer: The predicted value for Y When x = 4 is 33. ( y=33)

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

y = 6x + 9

Predict a value for y when x = 4

To predict the value we have to substitute the variable "x" for the number 4.

Mathematically speaking:

y = 6(4) +9

Solving:

Y = 24 +9

y = 33

The predicted value for Y When x = 4 is 33.

Feel free to ask for more if it´s necessary or if you did not understand something.

Solve for x. 2(x - 4) = 6(x + 2) -2 -1 -5 4
Iteru [2.4K]
Distribute on both sides

2x - 8 = 6x + 12

Move x to one side

-20 = 4x

Divide by 4

-5 = x

PLEASE HELP MEEEEE!!!!!!!

Answer:

  1. Cheese: 4\frac{3}{8}  
  2. Milk: 1\frac{2}{3}  
  3. Pasta: 6\frac{1}{4}

Step-by-step explanation:

Cheese:

  1. 1\frac{3}{4} = \frac{7}{4}  
  2. Set up a proportion: \frac{\frac{7}{4} }{4} = \frac{x}{10}  
  3. Cross multiply, then divide: 10 × 7/4 = 17.5, 17.5 ÷ 4 = 4.375
  4. 4.375 = 4\frac{3}{8}  

Milk:

  1. Set up a proportion: \frac{\frac{2}{3} }{4} = \frac{x}{10}  
  2. Cross multiply, then divide: 10 × 2/3 = 6\frac{2}{3}, 6\frac{2}{3} ÷ 4 = 1\frac{2}{3}  

Pasta:

  1. 2\frac{1}{2} = \frac{5}{2}  
  2. Set up a proportion: \frac{\frac{5}{2} }{4} = \frac{x}{10}  
  3. Cross multiply, then divide: 10 × 5/2 = 25, 25 ÷ 4 = 6.25
  4. 6.25 = 6\frac{1}{4}  

I hope this helps!

the total cost of a belt and a jacket was $82.78 if the price of the belt was $0.86 less than the jacket what was the price of t
Aloiza [94]
B=bellt price
j=jacket price

b+j=82.78

belt is 0.86 less than jacket
b=j-0.86
add 0.86 to both sides
b+0.86=j
sub
b+b+0.86=82.78
2b+0.86=82.78
minus 0.86 from both sides
2b=81.92
divid both sides by 2
b=40.96


belt=$40.96
