Answer:
Lin will run 1 mile in 8/55 of an hour
Noah will run 1 mile in 2/13 of an hour
Step-by-step explanation:
Here;
Lin ran 2 3/4 miles in 2/5 of an hour
he will run 1 mile in x hour
x * 2 3/4 = 2/5 * 1
2 3/4 = 11/4
x * 11/4 = 2/5
x = 2/5 * 4/11
x = 8/55 hour
For Noah
8 2/3 miles in 4/3 of an hour
1 miles in y hours
y * 8 2/3 = 4/3 * 1
y * 26/3 = 4/3
y = 4/3 * 3/26
y = 4/26 = 2/13
He will run 1 mile in 2/13 hours
Solve the system of equations..
y=x +45
y= 5x + 13
Answer:
x = 8
y = 53
Step-by-step explanation:
Sub y = x + 45 into the second equation
x + 45 = 5x + 13
Rearrange by collecting the like terms
45 - 13 = 5x - x
32 = 4x
Divide both sides by 4
x = 8
Sub x = 8 into first equation (y = x + 45)
y = 8 + 45
y = 53

An angle is 36⁰ less than its complement. What is the measure of the angle?
Answer:
27 degrees.
Step-by-step explanation:
If the angles are x and y then as they are complementary:
x + y = 90 - and we are given that:
x - y = 36 Adding the 2 equations:
2x = 126
x = 63.
So 63 - y = 36
y = 63 - 36 = 27.

Solve the equation a = m – n for the variable m.
Answer:
[tex]\rightsquigarrow\quad\sf{m=a+n}[/tex]
In-depth explanation:
Hi there, let's solve this equation.
Let's rearrange the equation a = m - n for m.
m - n = a
Add n to each side:
m = a + n
Therefore, m = a + n.

What is the measure of angle 1 in degrees?
Answer:
73 degrees
Step-by-step explanation:
The interior angle equals to 180. 73+37+ m<2 = 180. That means angle 2 is 70 degrees.
m<1 and m<C and equal due to alternate interior angles. That means angle 1 is 37 degrees.
We know angles 1 and 2 equal to 37 and 73. That means the angles are equal to the interior triangle. 70+37= 107. 180-107= 73 Degrees

The sugar sweet company is going to transfer its sugar to market. It will cost $4500 to rent trucks, and it will cost an additional $225 for each ton of sugar transported.
Let C Represent the total cost (in dollars), and let S represent the amount of sugar (in tons) transported. Write an equation relating C to S. Then use this equation to find a total cost to transport 14 tons of sugar.
Answer:
C=$7650
Step-by-step explanation:
Flat fee of 4500
S= 225x
x=14 tons of sugar
4500+225(14)=$7650 (C)
Equation:
C=4500+225(S)
Answer:
Total cost to transport 14 tons of sugar: $7650
Step-by-step explanation:
In the problem we are trying to find, C, the total cost to transport 14 tons of sugar.
$4500 to rent trucks
Additional $225 for each ton of sugar transported
C=4500+225(S)
We have our equation so now when begin to solve.
The problem gives us, S, the number of tons of sugar we are transporting, which is 14 tons.
So if it is an additional $225 for each ton of sugar then we would multiply 225 and 14. Which will look something like this:
C=4500+225(14)
Now we just simplify!
225(14)=3150
C=4500+3150
C=7650

What are the values of x and y?
a) 3x + 5y = 26
b) 2x + 2y = 12
Step One: We need to find a way to equate either the x terms of the y terms in each equation. Multiply equation a) by 2 and equation b) by 3 to form the following equations.
a) 6x + 10y = 52
b) 6x + 6y = 36
Step Two: Take equation b) from equation a) to eliminate the x component.
a) 6x + 10y = 52
- b) 6x + 6y = 36
0x + 4y = 16
y = 4
Step Three: substitute the value of y into either equation to find the value of x.
b) 2x + 2y = 12
2x + (2x4) =12
2x + 8 = 12
2x = 4
x = 2
x=2 y=4

Answer:
1. 23
2. 5.83 (5.8 rounded)
3. 1.18 (or 1.2 rounded)
4. unsure how to solve, sorry
Step-by-step explanation:
your formula: a^2+b^2=c^2
1. 20^2+13^2=c^2
400+169=569
(take the square root of 569)
c=23
2. 15^2+b^2=17^2
225+b^2=289
(subtract 225 from both sides)
b^2= 34
(take the square root of 34)
b=5.83 (or 5.8 rounded)
3. 0.2^2+b^2=1.2^2
0.04+b^2=1.44
(subtract 0.04 from bot sides)
b^2=1.4
(take the square root of 1.4)
b=1.18 (or 1.2 rounded)

Answer:

Step-by-step explanation:
What is the value of h(−2) when h(x)=3x+1?
Enter your answer in the box.
h(−2)=
Answer:
-5
Step-by-step explanation:
The answer is -5 because we have -2 as x. The function is h(x)=3x+1. 3 times -2=-6. When we add 1 to the result, we have -5 as the answer. Hope it helps!
The value of h(−2) when h(x)=3x+1 is h(-2) = -5
From the question,
The given function is h(x)=3x+1
To determine the value of h(-2), we will put x = -2 and evaluate
From
h(x)=3x+1
h(-2) becomes
h(-2)=3(-2) + 1
h(-2) = (3× -2) + 1
h(-2) = (-6) + 1
h(-2) = -6 + 1
h(-2) = -5
Hence, the value of h(−2) when h(x)=3x+1 is h(-2) = -5
