Answer:
25 gallons35 gallonsStep-by-step explanation:
You want the number of gallons of gas used by car 1 at 25 mpg and car 2 at 40 mpg when the total gas used for driving 2025 miles is 60 gallons.
SetupLet x represent the number of gallons used by car 2 at 40 miles per gallon. Then the gas used by car 1 is (60 -x). The number of miles driven is the product of miles per gallon and gallons used.
25(60 -x) +40x = 2025 . . . . total miles driven
SolutionSimplify the equation:
1500 +15x = 2025
15x = 525 . . . . . . . . . . subtract 1500
x = 35 . . . . . . . . . . divide by 15
60-x = 25 . . . . . gallons used by car 1
The first car used 25 gallons; the second car used 35 gallons.

Additional comment
The first car drove 25·25 = 625 miles; the second car drove 40·35 = 1400 miles.

if theresa's height is 60 inches tall and steve is 6 inches shorter than one and one third times theresa's height how tall is steve?
Steve is 74 inches tall
Answer:
74 inches tall
Step-by-step explanation:
First, let's find out what \(1\frac{1}{3}\) multiplied by 60 is.
60·\(1\frac{1}{3}\) =80
Then, let's subtract 6 from 80.
80-6=74
So, Steve is 74 inches tall.

A group of 24 students spent 1,296 minutes studying for an upcoming test. What prediction can you make about the time it will take 150 students to study for the test?
It will take them 174 minutes.
It will take them 2,592 minutes.
It will take them 8,100 minutes.
It will take them 8,745 minutes.
Answer:
It will take them 8,100 minutes.
Step-by-step explanation:
If it takes a group of 24 students 1,296 minutes to study for an upcoming test, it takes 54 minutes for each student. (=> 1,296/24 = 54)
150 x 54 minutes = 8,100 minutes.
It will take them 8,100 minutes.

On a map, 56 cm represents 64 miles. If the distance between two cities on the map is 28 cm apart, how many miles separate the cities?
Answer:
The answer is 32 miles
Step-by-step explanation:
First, you see that 56cm=64 miles
As u can tell 56-28=28
This means that you can just divide 64 by 2 which leads u to the answer of 32 miles
Answer:
32

What is the surface area of the following solid figure?
42 in. 2
62 in. 2
68 in. 2
59 in. 2
Answer:
the answer is 62 in. 2
Step-by-step explanation:
(the base is the triangle)
base:2*3/2 * 2 = 6
sides: 2.5*7*2 = 35
bottom: 3*7 = 21
base+sides+bottom
= 6+35+21

please write a function for the points (1/3,0) (-2 3/4,0) and (0,-5) and explain the steps.
thank you!
The function for the points are y = -15x - 5
How to determine the functionFrom the information given, we have that;
The points are;
(1/3,0) (-2 3/4,0) and (0,-5)
Using the point-slope form of a linear equation, we have;
y - y₁ = m(x - x₁)
Such that;
m is the slope of the liney - y₁ and (x - x₁) are the pointsUsing (1/3, 0) and (0, -5), we have that the slope is;
m = (0 - (-5))/0 -1/3)
expand the bracket
= 5 / (-1/3)
= -15
Now, take any of the given points and substitute the values
Using (1/3, 0), we get;
y - 0 = -15(x - 1/3).
y = -15x - 5.

The function for the points solved by (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)
We have given the points:
(1/3,0) (-2 3/4,0) and (0,-5)
Using the formula of linear equation
\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)
Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)
that is 1/3 = \(a\), 0 = \(a_{1}\) and
0 = \(b\), -5 = \(b_{1}\)
\(x\) refers to the slope of line (take any variable)
Now for finding the value of \(x\),
\(x=a-a_{1}/b-b_{1}\)
inserting the values,
\(x=[0-[-5]]/[0-1/3]\\x= -15\)
Substitute the value of \(x\) in the equation
\(a-0=-15[b-1/3]\)
By simplifying the equation, we get
\(a=-15b-5\)

Josh is trying to factor the expression -20a - 8.4 + 12.8b. He writes -4(5a + 2.1 + 3.2b).
a. What error did Josh likely make?
b. Factor the expression correctly.
c. Write an equivalent factored expression
Answer: =)
Step-by-step explanation:
a. The error Josh made in the problem is that he used a +3.2b. He was supposed to use -3.2b. Why? because the expression is -20a -8.4 + 12.8b, and he used -4 to make the equivalent factored expression. when you multiply +3.2 and a -4, the answer will turn out to be a negative number.
b. -20a -8.4 + 12.8b
c. The correct equivalent factored expression would be -4(5a + 2.1 -3.2b)
a. The error Josh makes is that he puts +3.2b when it’s supposed to be -3.2b because 12.8/-4 is -3.2b
b. -4(5a + 2.1 - 3.2)
c. -20a + 4.4
Question 13 of 15
A canoe travels 6 miles per hour downstream and 2 miles per hour upstream.
Let x represent the canoe's speed with no water current (still water) and y
represent the speed of the water current, in miles per hour. Then the situation
can be represented by this system of equations:
Choose the two correct options.
x + y = 6
x - y = 2
A. The speed of the canoe in still water is 4 miles per hour.
B. The speed of the canoe in still water is 2 miles per hour.
C. The speed of the water current is 4 miles per hour.
D. The speed of the water current is 2 miles per hour.
ANSWER : A AND D.
Step-by-step explanation:
the water current would be 2 mph and the canoe is 4 mph
See, 6miles downstream it would be 4mph of canoe + water boost ( 2 mph) = 6mph.
The canoe upstream would be 4mph - water resistance (2mph) = 2mph upstream.
The answers should be A and D.
