Answer:

Jasmine ran last week 37.2 miles

Step-by-step explanation:

Let

x ----> number of miles Rob ran last week

y ----> number of miles Jasmine ran last week

we know that

x=y-27.2 ----> equation A

x=10 ----> equation B

Substitute equation B in equation A and solve for y

10=y-27.2

y=10+27.2

y=37.2 miles

What is the expression in factored form? -20x^2 - 12x

artcher [175]

Answer:

-4x(5x-3)

Step-by-step explanation:

-20x^2 - 12x

-20x^2 = -4*5*x*x = -2*2*5*x*x

-12x = -4*3*x = -2*2*3*x

The common terms are -2*2*x = -4x. Whats left goes inside the parentheses

-4x(5x-3)

Lynna [10]

Answer:

11 6/9

Step-by-step explanation:

Daniel works in a market

He has large bags of potatoes that weighs 26 1/4

Daniel is going to sell them in smaller bags 9/4 pounds each

Therefore the number of smaller bags of potatoes in which Daniel would have filled can be calculated as follows

= 26 1/4 ÷ 9/4

= 105/4 ÷ 9/4

= 105/4 × 4/9

= 105/9

= 11 6/9

What is the axis of symmetry for f(x) = 2x2 − 4x + 5?

Romashka-Z-Leto [24]

Answer:

Axis of symmetry is

C) x = 1

Step-by-step explanation:

we are given equation as

$2x^2 -4x+5$

we can use axis of symmetry formula

Let's assume we are given quadratic equation as

$y=ax^2+bx+c$

Axis of symmetry is

$x=-\frac{b}{2a}$

now, we can compare both equations

and we get

$a=2,b=-4$

now, we can find axis of symmetry

$x=-\frac{(-4)}{2\times 2}$

$x=-\frac{(-4)}{4}$

$x=1$

Three numbers are in the ratio 3:9:10. If 10 is added to the last number, then the three numbers form an arithmetic progression.

MrRa [10]

Answer:

 The numbers are 6, 18, and 30 

Step-by-step explanation:

If the three numbers are in the ratio of 3:9:10,

let the numbers be 3x, 9x and 10x.

If 10 is added to the last number to form an arithmetic progression

Then, 3x 9x (10x+10) are the progression

The common difference of an arithmetic progression (d) = T₂ - T₁ = T₃ - T₂

T₂-T₁ = T₃ - T₂ .............. Equation 1

Where T₁ = first term of the progression, T₂ = Second term of the progression, T₃ = third term of the progression

Given: T₁ = 3x, T₂ = 9x, T₃ = 10x +10

Substituting these values into equation 1

9x-3x = (10x+10)-9x

Solving the equation above,

3x = 10+x

3x-x = 10

2x = 10

x = 10/2

x = 2.

Therefore the numbers are 6, 18, and 30
