working together two mathletes solve 32 math problems in a certain amount of time how many problems will 3 mathletes solve if they together at the same rate for the same amount of time
If they together at the same rate for the same amount of time, they will solve 48 math problems,
From the question, we can see that two mathletes solve 32 math problems in a certain amount of time, this can be written as:
2 mathletes = 32 math problemsIn order to determine the number of problems for 3 mathletes, this is expressed as:
3 mathletes = xDIvide both expressions:
2/3 = 32/xCross multiply
2x = 3* 32
x = 3 * 16
x = 48math problems
Hence if they together at the same rate for the same amount of time, they will solve 48 math problems,

A chef is going to use a mixture of two brands of Italian dressing. The first brand contains 6% vinegar, and the second brand contains 11% vinegar. The chef wants to make 380 milliliters of a dressing that is 7% vinegar. How much of each brand should she use?
Answer: To make a 310mL mixture that contains 8% vinegar, use 186mL of the first brand and 124mL of the second brand.
Step-by-step explanation:We want the total mixture to be 310mL so: F + S = 310
Also, you want the total mixture to contain 8% vinegar so: .06F + .11S = .08(310)
Now, we can solve the system of equations using substitution.
F + S = 310
.06F + .11S = .08(310)
F = 310 - S [solve 1st equation for F]
.06(310 - S) + .11S = .08(310) [substitute into 2nd equation]
18.6 -.06S +.11S = 24.8
.05S = 6.2
S = 124
F + 124 = 310 [substitute answer for S back into original equation]
F = 186
HELP ME GUYS PLEASE! :)
Answer:
4x + 5y = 19 - (x + 5y = 16)
4x - x = 3x
5y - 5y = 0
19 - 16 = 3
3x = 3
x = 1
4x + 5y = 19
4(1) + 5y = 19
4 + 5y = 19
5y = 15
y = 3
Solution: (1,3)
Step-by-step explanation:
4x + 5y = 19 - (x + 5y = 16)
4x - x = 3x
5y - 5y = 0
19 - 16 = 3
3x = 3
x = 1
4x + 5y = 19
4(1) + 5y = 19
4 + 5y = 19
5y = 15

A student says that the solution of 375 = x – 28 is 347. Explain the student’s error and find the correct answer
Answer:
x = 403
Step-by-step explanation:
We can start off by rewriting the equation as
x - 28 = 375
Next, we can further restate it as
375 + 28 = x
So, all we need to do to find the value of x is add 375 + 28, which is 403
Student Error
The student made the error of rewriting the equation incorrectly.
He/She/They subtracted 28 from 375 instead of adding.
Thus, they got 347
Given h(x)=4x-1, solve for x when h(x)=-9
Step-by-step explanation:
h(x) = 4x - 1
given,
h(x) = -9
now,
h(-9) = 4(-9) - 1
→ -36 - 1
→ -37
hope this answer helps you dear, take care!
Answer:
x = - 2
Step-by-step explanation:
Given h(x) = 4x - 1 and h(x) = - 9, then equating right sides gives
4x - 1 = - 9 ( add 1 to both sides )
4x = - 8 ( divide both sides by 4 )
x = - 2
is 8/24 greater or 8/20
Answer:
8/20
Step-by-step explanation:
the 8s may be the same, but because the denominator 20 is smaller than 24, 8 takes up more of it. another way to check is that 8/24 as a decimal is .33 repeating, but 8/20 as a decimal is 0.4.
0.4 is more than .33 repeating. reaffirming that 8/20 is bigger

Amount Juno Owed for a Taxi Miles Amount Owed (dollars) 1 2. 5 2 2004. 75 3 7 4 9. 25 5 11. 5 Yes, because the amount owed changes by 1 every time the miles change by 2. 25. Yes, because the amount owed changes by 2. 25 every time the miles change by 1. No, because the amount owed does not change by 1 every time the miles change by 2. 25. No, because the amount owed does not change by 2. 25 every time the miles change by 1.
Linear functions are represented by constant rates.
The true statement is (d) No, because the amount owed does not change by 2.25 every time the miles change by 1.
From the table, we can see that:
As the number of miles increase by 1, the amount owed increases, but it does not increase at a constant rate of 2.25.
This means that, the table does not represent a linear function.

What is the slope of the line that passes through the points (5, 6)(5,6) and (5, 9) ?(5,9)? Write your answer in simplest form.
Answer:
Step-by-step explanation:
Slope is defined as the "Rise" over the "Run" of a straight line. The Rise is the change in y, and the Run is the change in x. For the given points:
(5,6) and (5,9) the Rise and Run are (going from left to right).
Rise (9-6) = 3
Run = (5-5) = 0
The slope is 3/0, which is undefined (can't divide by zero).

x= -14.5
Step-by-step explanation:
-1.3=x-(-13.2)
the two - signs cross eachother out, making it a +.
making the equation -1.3=x-(-13.2) turn into -1.3=x+13.2.
so you should automatically know your x is going to have to be negative.
What I did:
13.2+1.3=14.5,
but since the 1.3 was actually negative, (-1.3) the 14.5 will turn negative, making it -14.5

Answer:
15π/2 ft
Step-by-step explanation:
Arc length is given by the formula ...
s = rθ . . . . . r = radius; θ = central angle in radians
A 135° arc has a radian measure of (135)(π/180) = 3π/4. The radius of a circle with a 20 ft diameter is (20 ft/2) = 10 ft. So, the arc length is ...
s = (10 ft)(3π/4) = 30π/4 ft = 15π/2 ft
