Lanie works part-time at Sweet Treats Catering. She earns $13.25 per hour and work 25 hours a
week. She is paid semi-monthly.
a. Calculate her gross pay for 1 paycheck. Show all your math calculations.
Answer:
Semi-monthly gross pay = $662.5
Step-by-step explanation:
Given:
Earning per hour = $13.25
Number of hours per week = 25 hours
Find:
Semi-monthly gross pay
Computation:
Assume two week in semi-month
So,
Total working hour = 2(25)
Total working hour = 50 hours
Semi-monthly gross pay = Total working hour × Earning per hour
Semi-monthly gross pay = 50 × 13.25
Semi-monthly gross pay = $662.5

Help? Please? This is algebra math
Answer:
You count the blocks and then put the amount of blocks before:)
(That sounds confusing but it sounds harder than it is)
The answer would be 3xy + 4x
Step-by-step explanation:
How many xy blocks are there? yea there's 3 so you do 3xy
you can't add xy and x blocks together because xy is a different unit than x (xy is x times y) so then you'd count the other x blocks seperately
(I'm sorry if I'm wrong on this lol)
y= 4x-3?

Step-by-step explanation:
the slope of a hill 3/190. The Hill has a ride of 400m. What is the horizontal distance covered by the hill?
Answer:
its 5
Step-by-step explanation:
The hill with a rise of 400m and a slope of 3/190 covers approximately 25333.33 meters horizontally.
Slope is a term used to describe how steep or inclined a line is on a graph. It shows the proportion of the rise to the run or vertical change, between any two points on a line. The slope is a fundamental idea in geometry, algebra and calculus; it shows how much the line rises or falls for each unit of horizontal distance. A slope of zero denotes a horizontal line while positive slopes denote upward inclines, negative slopes denote downward inclines, and vice versa.
Slope = rise / run
Given that the slope of the hill is 3/190 and the rise is 400m, we can set up the equation:
3/190 = 400 / run
run = 400 / (3/190) = 400 × (190/3)
= 400 × 63.33 ≈ 25333.33 meters
the horizontal distance covered by the hill is approximately 25333.33 meters.

Answer:
B & D
Step-by-step explanation:
Options B and D have a solution from the given set of equations.
We need to find from the given which equation does not have solutions.
How to determine whether the equation has no solution?Solve the given equation for x. If you get any value then the equation has a solution.
From option (A):
-60x+32=-60x+60
⇒-60x+60x=60-32
By simplifying the above equation we get no x value. So, there are no solutions.
From option (B):
-60x+32=32x-60
⇒-60x-32x=-60-32
⇒-92x=-92
⇒x=1
From option (C):
-60x+32=-60x-32
By simplifying the above equation we get no x value. So, there are no solutions.
From option (D):
-60x+32=32x+60
⇒-92x=28
⇒x=0.304
Therefore, options B and D have a solution.

A system of equation is shown: 2x = -y + 6 -4x + 3y =8 what is the solution tonthis system of equations? (-1, -4) (1, 4) (4, 4) (-4, -1)
Answer:
(1 , 4)
Step-by-step explanation:
2x = -y + 6
-4x + 3y = 8
2x = -y + 6
2x - 6 = -y
-2x + 6 = y
-4x + 3y = 8
-4x + 3(-2x + 6) = 8
-4x - 6x + 18 = 8
-10x + 18 = 8
-10x = -10
x = 1
-2x + 6 = y
-2(1) + 6 = y
-2 + 6 = y
4 = y

Step-by-step explanation:
X cannot equal itself minus 5, in the same way if we replace it by let's say, 6...
6 does not equal 6-5 (1)........ and by the way in this specific equation 6 is just an example it does not matter what you replace it with, x can never = x-5

Three times a number increased by one is between negative eight and seven find all the numbers.
All the numbers that makes the statement true are given by?
Please hurry this is on my exam
This is about absolute value inequalities.
The set of possible values of x that make the statement true are; x = {-2, -1, 0, 1}
Let the number in the question be x.We are told that when it is multiplied by 3 and 1 added to it, it is between - 8 and 7. This means it is greater than -8 but less than 7.
Thus;
3x + 1 > -8 - - - (eq 1)
3x + 1 < 7 - - - (eq 2)
Let's find range of x from eq 1;3x + 1 > -8
Subtract 1 from both sides to get;
3x > -9
x > -9/3
x > -3
Similarly, let's find the range of x from eq 2;3x + 1 < 7
Subtract 1 from both sides to get;
3x < 7 - 1
3x < 6
x < 6/3
x < 2
Thus, we can write that;
-3 < x < 2
Thus, the set of possible values of x are; x = {-2, -1, 0, 1}
