Step-by-step explanation:
Franky and Francesca applied to the same college. They looked up the average SAT score of students admitted to that college. Franky’s SAT score was 140 points above the average score. Francesca’s SAT score was 40 points below the average score. Which expression represents the difference in their scores?
❘-40 - 140❘
-❘140❘ - ❘40❘
-❘140❘ + ❘-40❘
❘140 - 40❘
Answer:
❘-40 - 140❘
Step-by-step explanation:
Given that,
Franky’s SAT score was 140 points above the average score.
Francesca’s SAT score was 40 points below the average score.
We need to find the expression that represents the difference in their scores. It can be calculated as follows :
d = ❘-40 - 140❘
= -180
Hence, the correct option is (A) "❘-40 - 140❘".

Answer:
A.y=|x|+7
Step-by-step explanation:
Solve the following system of equations:
4x + 3y = 17
3x + 2y = 13
ANSWER:
(x,y) = (5,-1)
Answer:
(5, -1)
Step-by-step explanation:
Solve the system of equations by elimination.
4x + 3y = 17
3x + 2y = 13
Multiply the top equation by -3 and the bottom equation by 4:
-12x - 9y = -51
12x + 8y = 52
Add these together:
-y = 1
y = -1
Plug in -1 as y into one of the equations, and solve for x:
4x + 3y = 17
4x + 3(-1) = 17
4x - 3 = 17
4x = 20
x = 5
So, the solution is (5, -1)
Example :
3X+4 X=2
3(2)+4

Line Ris represented by the equation y ==x+2. Line S is perpendicular to Line R, and passes through
the point (-6,4). What is the equation for Line S?
A. y =
B. y = x +6
C. y=-*-5
D. y = -x + 8
Answer:
y = -x - 2
Step-by-step explanation:
y = x + 2 {Compare with y = mx + c}
Slope = m1 = 1
Slope of the line S = m2 = -1/m1 = -1/1 = -1
(-6 , 4)
y -y1 = m (x -x1)
y - 4 = (-1)(x - [-6] )
y -4 = (-1)(x + 6)
y -4 = (-1)*x + (-1) *6
y - 4 = -x - 6
y = -x - 6 + 4
y = -x - 2

roup of softball players are training on a square-shaped sports ground with sides measuring 100 yards each. The players run around for 10 minutes to warm up. How many laps around the sports ground do they run given their average speed is 5 yards per second? Please add an explanation. I will mark the brainliest to whoever's answer is best and YOU GET 50 Points.
Answer:
7.5 laps
Step-by-step explanation:
First, you wanna figure out how many yards is in one lap
to do this, you would multiply 100 and 4 (four because there's four equal sides in one lap)
100 x 4 = 400
You know their speed is 5 yards per second, so you wanna find out how many seconds they will be running
to do this, you multiply 60 (sixty because there's sixty seconds in one minute) and 10 (ten because that's the given amount of minutes)
60 x 10 = 600 seconds
now to found out how much they will run in 10 minutes you will multiply 600 by 5
600 x 5 = 3000 yards
now to find how many laps this is, you can divide 3000 yards by 400 yards
3000 ÷ 400 = 7.5 laps
annual sales for a company are $149,999 and are increasing at a rate of 6% per year. write an exponential growth function to model this situation. then, find the annual sales after 7 years.
Answer:
S(t) = 149999(1.06)^t$225543Step-by-step explanation:
Initial value is $149999Increase rate is 6% per year = 1.06 timesThe model of the growth is:
S(t) = 149999(1.06)^t, where S- amount of annual sales, t- time in years, 1.06- growth rate per yearAnnual sales after 7 years:
S(7) = 149999(1.06)^7 = $225543Is -6 a solution for the equation 3(2x - 8)= -4(-6 +21)?
Answer:
YeS, it is a solution
Step-by-step explanation:
Here, we want to check if -6 is a solution to the question
What we have to do is to replace x by -6
If what we have on the left equals that on the right, then -6 is a solution
Thus, we have it that;
3(2(-6) -8)
= 3(-12-8)
= 3(-20) = -60
for the right hand side
-4 (15) = -60
This means both sides are equal and that -6 is a solution
Choose Yes or No to tell whether the symbol will be reversed when the variable is isolated in each inequality. –10.5 < 3a b6 ≤ 7 –4.5c > 9 –215 ≤ –52d
Answer:
1). No, symbol won't be reversed
2.) No, symbol won't be reversed
3.) yes, symbol will be reversed
4.) No, symbol won't be reversed
Step-by-step explanation:
1.)
-10.5 < 3a
-10.5 /3 < 3a /3
-3.5 < 3 (No)
2.)
b/6 ≤ 7
Multiply both sides by 6
b/6 * 6 ≤ 7 * 6
b ≤ 42 (No)
3.)
-4.5c > 9
Dibide both sides by - 4.5
-4.5c / - 4.5 > 9/-4.5
c < 2 (yes)
4.)
–21/5 ≤ –5/2d
Multiply both sides by 2/5
-21/5 * 2/5 ≤ - 5/2d * 2/5
-21/2 ≤ - d
21/2 ≤ d (No)
A number cube is labeled 1 through 6. What is the probability of NOT
rolling a 2?
Answer:
Step-by-step explanation:
each of the 6 number has a 1/6 chance of being rolled
1 2 3 4 5 6
1/6 1/6 1/6 1/6 1/6 1/6
Every time the cube is rolled there is a 6/6 chance of any number comes up
1/6 + 1/6 + 1/6 + 1/6 + 1/6 + 1/6 = 6/6 or 1
What is the probability of NOT rolling a 2? Any other number
1 2 3 4 5 6
1/6 + 0 + 1/6 + 1/6 + 1/6 + 1/6 = 5/6 or 0.8333

What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.com
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
If the recipe makes 12 biscuits and Jamila wants to make 36 biscuits, she needs to triple the recipe.
To triple the amount of butter, we can multiply 125 g by 3:
125 g x 3 = 375 g
Therefore,
Jamila needs 375 g of butter to make 36 biscuits.
