What is the value of x in the solution to the system of equations? 4x - 2y = 5 y = 3x - 1
Answer:
X = 7
Step-by-step explanation:
Please mark brainliest.
Answer:
[tex]\huge\boxed{\sf x = -2}[/tex]
Step-by-step explanation:
4x - 2y = 5 -------------------------------(1)
y = 3x - 1 ----------------------------------(2)
Put Eq. (2) in (1)
4x - 2(3x-1) = 5
4x - 6x + 1 = 5
-2x + 1 = 5
Subtracting 1 to both sides
-2x = 5 - 1
-2x = 4
Dividing both sides by -2
x = 4 / -2
x = -2

~AnonymousHelper1807Reese had $42 in his pocket orl Sunday night. He spent $6.50 every day for lunch.
Which of the following equations best describes the relationship between d, the
number of days since Sunday, and m, the amount of money remaining?
The required equation is m = 42 - 6.50d which is the correct answer would be an option (C).
What is the Linear equation?A linear equation is defined as an equation in which the highest power of the variable is always one.
We have been given that Reese had $42 in his pocket on Sunday night. He spent $6.50 every day for lunch.
Let d represents the number of days since Sunday, and m represents the amount of money remaining
Reese has 42 total and it subtracts by 6.50$ every day
According to the given question,
The linear equation would be as
m = 42 - 6.50d
The above model equation is the relationship between d, the number of days since Sunday, and m, the amount of money remaining
Therefore, the required equation is m = 42 - 6.50d.

Answer:
787.5
Step-by-step explanation:
Givens
The bottom part of the figure is a trapezoid. Solve it first
a = 15 cm
b = 34 cm
h = 19 cm
Formula
Area = 1/2 (a + b)*h
Solution Trapezoid
area = 1/2 (15 + 34)*19
Area = 1/2 * 49 * 19
Area = 465.5
Remark
The top half of the figure is a parallelogram.
Formula
Area = base * height
Givens
base = 23
height = 14
Solution
Area = 23 * 14
Area = 322
Total Area
Total Area = 322 + 465.5
Total Area = 787.5

how do I solve for N 1/2(n+4)=6?
Answer:
8
Step-by-step explanation:
Get rid of the denominator first. -Multiply both side by 2-
1/2 × 2 = 1 (n + 4) ----- n + 4
6 × 2 = 12
n + 4 = 12
Now solve for N
N = 12 - 4
N = 8

A random sample of 20 married women showed that the mean time spent on housework by them was 29.8 hours a week with a standard deviation of 6.7 hours. If the margin of error is 3.14, find a 95% confidence interval for the mean time spent on housework per week by all married women.
Answer:
95% confidence interval for the mean time spent on housework per week by all married women.
( 26.66 , 32.94)
Step-by-step explanation:
Step(i):-
Given random sample size 'n' = 20
Mean of the sample (x⁻ ) = 29.8 hours
Standard deviation of the sample (S) = 6.7
Given Margin of error = 3.14
Step(ii):-
95% confidence interval for the mean is determined by
[tex](x^{-} - t_{0.05} \frac{S}{\sqrt{n} } , x^{-} +t_{0.05} \frac{S}{\sqrt{n} })[/tex]
We know that margin of error is determined by
[tex]M.E = \frac{t_{0.05}XS.D }{\sqrt{n} } = 3.14[/tex]
Now 95% confidence interval for the mean time spent on housework per week by all married women.
[tex](29.8 - 3.14 , 29.8+3.14)[/tex]

just solve for b basically, also the 3/2 and 3/4 is a fraction so they're over eachother but it wont let me do that on here so yeah. also sorry this is very late so i dont know if im any help.
The required function h(a) is a = -4b +18
A simplified function h for a-5=-4b+13 to be determine.
What are functions?A function is defined as for every input their is a certain output.Function is a type of relation, or rule, that maps one input to specific single output.
Here, we have a-5=-4b+13
a−5=−4b+13
a = -4b + 13+ 5
a = -4b +18
Thus, the required function h(a) is a = -4b +18

The train station clock runs too fast and gains 8 minutes every 10 days.
How many minutes and seconds will it have gained at the end of 4 days?
Answer: 3 minutes and 12 seconds
Step-by-step explanation: You can see 8 minutes every 10 days as a fraction (8/10). This can be simplified to 4/5, meaning that the amount of time gained will be 4/5 of the # of days that have passed. 4/5 of 4 days is 3.2 minutes, and that can be converted to 3 1/5. 60 seconds divided by 5 is 12 seconds, meaning that 1/5 of a minute is 12 seconds. Therefore, the answer is 3 minutes and 12 seconds.
