Increase 130 by one fifth​

Answer:

14. y= 3/5x-2

15. y= -1x-2

17. -1/2

Step-by-step explanation:

Since you have a point and a slope put it in point-slope form first.

Point-slope form: y-y1=m(x-x1)

Then solve for y.

Then you'll get the slope-intercept form.

For number 17 use the slope-intercept form y=mx+b

rise/run= m= y2-y1/x2-x1

Answer:

Area of rectangular garden = lxb = 10*5

                                             = 50 sq. inch

when area increases by six times

new area = 50*6 = 300 sq inches

now,

let x be increasement in both  length and width

(5+x) (10+x) = 300

50 + 5x + 10x + x² = 300

x² + 15x - 250 = 0

x²+ 25x-10x -250 = 0

x(x+25) - 10 (x+25) = 0

( x-10) (x+25) = 0

either x + 25 =0

x = -25 length can be negative

0r x-10 = 0

x = 10

so 10 inches is increase on both side

Answer:

Linda, Julie, Jenna, Karl

Step-by-step explanation:

Here, we want to list the students in order from lowest to highest

The key here is to have the scores in the same form, let us say decimals for ease of comparison

Jenna: 85% = 85/100 = 0.85

Linda’s= 32/40 = 80% = 0.8

Karl = 7/8 = 0.875

Julie = 0.83

So from lowest to highest, we have;

Linda, Julie, Jenna, Karl

Answer: 6 (z+13)

Step-by-step explanation:

Answer:

Step-by-step explanation:

10-z=6

We move all terms to the left:

10-z-(6)=0

We add all the numbers together, and all the variables

-1z+4=0

We move all terms containing z to the left, all other terms to the right

-z=-4

z=-4/-1

z=+4

Answer:

The slope of the line represented by y = -5x is "-5".

Step-by-step explanation:

y=mx+b

M=slope

b=Y-intecerpt

Answer:

For the first 2 questions, you need to find the square roots of those numbers. The  second 2 question, you need to do those problems. Remember that absolute value is always positive. Then, plot those numbers on the coordinate plain.

Answer:

The inequality [tex]\frac{8}{4}\:<\frac{5}{2}\:[/tex]  is true.

Step-by-step explanation:

Given

[tex]\frac{8}{5}<\frac{9}{10}[/tex]

FALSE

Reason: 8/5 or 1.6 is greater than 9/10 or 0.9  

[tex]1>\frac{6}{5}[/tex]

FALSE

Reason: 1 is smaller than 6/5 or (1.1)

[tex]\frac{5}{2}<2\frac{1}{2}[/tex]

converting mixed number to improper fraction

[tex]\frac{5}{2}<\frac{5}{2}[/tex]

FALSE

Reason: 5/2 can not be less than 5/2

[tex]\frac{8}{4}\:<\frac{5}{2}\:[/tex]

[tex]2<\frac{5}{2}[/tex]

TRUE

Reason: 2 is indeed smaller than 5/2 or 5.2        ∵ 5/2 = 2.5

Therefore, inequality [tex]\frac{8}{4}\:<\frac{5}{2}\:[/tex]  is true.

Answer:

9.1 = a+4

Step-by-step explanation:

The right side has two different values, variable a, constant 4.

The left side has the constant 9.1.

If both sides are equal, then

a + 4 should equal 9.1

Answer:

9.1 = a+4

Answer:

Grant's weekly allowance is $20.

Step-by-step explanation:

We know that Grant ended with $15. We can say that Grant's weekly allowance is x.

x/2 + 5 = 15

Now to solve:

x/2 + 5 - 5 = 15 - 5 (subtract 5 from both sides to isolate the x/2)

x/2 = 10

x/2 * 2 = 10 * 2 (multiply both sides by 2 to isolate the x)

x = 20

Grant's weekly allowance is $20.

Answer:

16

Step-by-step explanation:

To find 80% of 20, multiply .80 x 20

.80×20 = 16

This is how you multiply percentages--put the decimal point 2 places to the left, then multiply.  In this case, you're looking at 80%, so move the decimal point two places to the left

80.0 becomes .80

Then multiply that by the number you're trying to find the percentage of

Answer:

x = 35

Step-by-step explanation:

we know that all triangles add up to 180

you first need to make an expression in which the angles equal 180

105 + 140 + x = 180

         145 + x = 180

subtract 145 from both sides

                  x = 35
