A hybrid SUV can travel 400 miles on a 15-gallon tank of gas. How many miles can it travel on 6 gallons of gas?
Answer:
160miles
Step-by-step explanation:
400miles uses15g what about 6g.
Using cross multiplication. Multiply 6x400/15 = 160miles
Answer:
160 miles
Step-by-step explanation:
If it travels 400 miles on 15 gallons, then it will travel x miles on 6 gallons
400 miles -> 15 gallons
x miles -> 6 gallons
15 * x = 6 * 400
15x = 2400
x = 2400 / 15
x = 160 miles
Simplify the expression:
17 – (-5x + 2)
Answer:
5x + 15
Step-by-step explanation:
Let's simplify step-by-step.
17−(−5x+2)
Distribute the Negative Sign:
=17+−1(−5x+2)
=17+−1(−5x)+(−1)(2)
=17+5x+−2
Combine Like Terms:
=17+5x+−2
=(5x)+(17+−2)
=5x+15
Answer:
=5x+15
Answer:
-3
Step-by-step explanation
You would first used distribuve property in the parenthisis.
Because there is a minus sign outside of the parenthisis, it would become (5x-2)
Combine like terms
15+5x=0
Subtract 15 from both sides
5x=-15
Divide 5 to get x
5x(/5)= -15(/5)
x=-3

In a high school stadium there are 1575 seats. There are two and a half times as many seats in the home section as there are in the visitor section. Which system of equations could be used to determine the number of seats in the home section, h, and the number of seats in the visitor section, v, in the stadium?
Answer:
h = 1,125
v = 450
Step-by-step explanation:
Total number of seats = 1575
h = number of seats in the home section
v = number of seats in the visitor section
There are two and a half times as many seats in the home section as there are in the visitor section.
h = 2 1/2 * v
h = 2 1/2v
Total = h + v
1575 = 2 1/2v + v
1575 = 3 1/2v
1575 = 7/2v
v = 1575 ÷ 7/2
= 1575 × 2/7
= (1575*2) / 7
= 3150 / 7
= 450
v = 450
h = 2 1/2v
= 5/2*450
= 2250/2
= 1,125
h = 1,125

Answer:
-17√2 /26 or -0.9247 to the nearest ten thousandth.
Step-by-step explanation:
The hypotenuse of the right triangle in which tan x = 2/3 is √(2^2 + 3^2)
= √13 so sin x = 2/√13 and cos x = 3/√13
sin2x = 2sinxcos
= 2* 2/√13 * 3/√13
= 12/13.
cos2x = cos^2x - sin^2x
= 9/13 - 4/13
= 5/13.
sin(2x + 5π/4)
= sin2x cos5π/4 + cos2x sin5π/4
= 12/13 * -1/√2 + 5/13 * -1/√2
= -12 / 13√2 - 5 / 13√2
= -17/13√2
= -17√2 /26.

What is linear inequality?Linear inequality refers to the relation between a linear algebraic expression to some known value that contains inequality sign.
Unlike a linear equation it can have a range of values inside an interval.
The given inequality can be solved as follows,
4x - 5 ≥ 7
Subtract 7 from both sides to obtain,
4x - 5 - 7 ≥ 0
=> 4x - 12 ≥ 0
=> 4x ≥ 12
=> x ≥ 3
The graph for the given inequality is shown as below,
Hence, the solution for the given inequality is x ≥ 3.

Solve for p in 2.5+3(5 – 2.1p) = -13.37
Answer: p = 4.9
Step-by-step explanation:
2,5 + 3(5-2.1p) = -13,37
2,5 + 3(5-2.1p) - 2,5 = -13,37 - 2,5
3(5-2.1p) = -15,87
3(5-2.1p) / 3= -15,87 /3
5-2.1p = -5.9
5+5.29 = 2.1p
(5+5.29 ) /2.1 = 2.1p /2.1
4.9 = p

In exercises 27-30, three vertices of DEFG are given. Find the coordinates of the remaining vertices: D(-2,-4), F(0,7), G(1,0)
Answer:
[tex]E =[/tex] [tex](-3,3)[/tex]
Step-by-step explanation:
Given
Parallelogram: DEFG
[tex]D(x_1,y_1) = (-2,-4)[/tex]
[tex]F(x_3,y_3) = (0,7)[/tex]
[tex]G(x_3,y_4) = (1,0)[/tex]
Required
Find the coordinates of [tex]E(x_2,y_2)[/tex]
To do this, we make use of mid-point formula which is:
[tex]M = (\frac{x_1+x_3}{2},\frac{y_1+y_3}{2})= (\frac{x_2+x_4}{2},\frac{y_2+y_4}{2})[/tex]
This gives:
[tex](\frac{-2+0}{2},\frac{-4+7}{2})= (\frac{x_2+1}{2},\frac{y_2+0}{2})[/tex]
[tex](\frac{-2}{2},\frac{3}{2})= (\frac{x_2+1}{2},\frac{y_2+0}{2})[/tex]
Multiply through by 2
[tex]2 * (\frac{-2}{2},\frac{3}{2})= (\frac{x_2+1}{2},\frac{y_2+0}{2})*2[/tex]
[tex](-2,3) = (x_2+1,y_2+0)[/tex]
[tex](-2,3) = (x_2+1,y_2)[/tex]
By comparison:
[tex]-2 = x_2 + 1[/tex] and [tex]3= y_2[/tex]
So, we have:
[tex]-2-1=x_2[/tex] and [tex]3= y_2[/tex]
[tex]-3 = x_2[/tex] and [tex]3 = y_2[/tex]
This gives:
[tex]x_2 = -3[/tex] and [tex]y_2 =3[/tex]
Hence, the 4th coordinate is: [tex](-3,3)[/tex]
