Answer: 25+3x =133
Step-by-step explanation:
Let x = the amount Rodney saved last month
Cost of camera Rodney wants to buy= $133 , which is $25 more than 3 times the amount he saved last month.
i.e. 25+3(amount Rodney saved last month) = Cost of camera (in dollars)
i.e. 25+3x =133 (in dollars)
Hence, the equation could be used to solve for x : 25+3x =133

Find the slope and y-intercept of the line whose equation is given.
y= - 7x-9
Determine the slope. Select the correct choice below and fill in any answer boxe
A. m=
(Type an integer or a fraction.)
OB. The slope is undefined.
Answer:
Slope = -7
y-intercept = -9
Step-by-step explanation:
The slope formula is y = mx + b where m is the slope value and b is the y-intercept value. In this case, since both values have a negative sign in front of them, they are both negative.
y = mx + b
y = -7x - 9
m = -7 which is the slope
b = -9 which is the y -intercept
Ignore the blue thing
Answer:
g(-9) = -43
Step-by-step explanation:
Plug the -9 where the x are at
g(-9 )= 4(-9) - 7
g(-9) = -36 - 7
g(-9) = -43
Simipified the exprestion -1.7+(-6.3).On the test when maureen simipified the exression she got -4.6. What mistake did maureen likley make when she simipified the question
Answer:
Maureen ignored the negative(minus) sign in 1.7 thereby turning it into positive 1.7
Step-by-step explanation:
-1.7 + (-6.3)
Correct simplification
-1.7 + (-6.3)
Open parenthesis
= - 1.7 - 6.3
= -8
NOTE:
- * + = -
- * - = +
+ * - = -
+ * + = +
Maureen's simplification
-1.7 + (-6.3)
= 1.7 - 6.3
= -4.6
Maureen ignored the negative(minus) sign in 1.7 thereby turning it into positive 1.7

Graham drove 42 1/3 miles in 1 1/3 hours
How many hours did he take to drive one mile?
Answer: 1.89 minutes
Step-by-step explanation: If we take 1 and 1/3 hours and turn that into minutes we get 80 minutes we then divide it by the number of miles 42 1/3. We would get about 1.89, so it took about 1.89 minutes

7. Of the three explanations below, which person gives the best explanation of why the LSRL is the best line of best fit?
Explain your choice.
Thomas: The LSRL is the best line of
best fit because it touches the most
points on a scatterplot when graphed.
Keene: The LSRL is the best line of best fit
because it has the smallest value for all the
squared residuals added together.
Ella: The LSRL is the best line of best fit because the sum of the residuals is closest to zero when they are all
added together.
Answer:
Ella
Step-by-step explanation:
IT goes more into detail on why the LSRL is best line of fit
Reuben drove 845 miles in 13 hours. At the same rate, how many miles would he drive in 11 hours? miles
Answer:
715 miles in 11 hours
Step-by-step explanation:
845 ÷13 = 65
this means that in 1 hours Reuben drives 65 miles.
65x11= 715.
Saiful deposits a sum of RM 5000 in a bank with interest rate of 4% per annum. What is the interest
earned by Saiful after 3 months ?
Answer:
Saiful has earned RM 50 after 3 months.
Step-by-step explanation:
We are given the following:
x = 5000
y = 4% per 12 months (annually)
[Convert 4%/1 yr to three months]
Because 1 year = 12 months = 4% then:
3 months is 25% of 12 months, so find 25% of 4%.
25% of 4% is 1%
y = 1%
[Multiply x by y]
x * y = 5000*1% = 5050
[Subtract 5050 by the original, 5000]
5050 - 5000 = 50
Saiful has earned RM 50 after 3 months.
NEED HELP PLEASE!!! Lionel created a scatter plot and drew a line of best fit, as shown.
What is the equation of the line of best fit that Lionel drew?
Answer: A.
Y=-2x+16
Step-by-step explanation:
You gotta find the pretty points on the line of the linear function. Then you have to find the slope (rise over run) with those pretty points. Then you have to use a coordinate (I used 6,4) to find the y intercept. Then you solve the equation, by plugging in all the numbers :) hope this helps.

How many quaters are in 4 and 3 over 4
Answer:
19
Step-by-step explanation:
If you're asking how many quarters in 4 3/4
In 1 there are 4 quarters so do 4 multiplied by the 4 quarters which is 16. In 3/4 we have 3 quarters so 16 add the 3 is 19.

Find the error in the calculations shown, and then evaluate the expression correctly.
-3.8 - (7.2 - 10 3/8
3.8+(-7.2 - 10 3/8
(-3.8+(-7.2)) – 10 3/8
- 11 - 10 3/8
11+ 10 3/8
21 3/8
Answer:
-3.8 - (7.2-10 3/8)
-3.8+(-7.2+10 3/8) this is the error, it's positive 10 3/8, not negative, then you should solve what's in the parentheses first
I simplified 10 3/8 into 83/8 and then 10.375
-3.8+(-7.2 + 10.375)
-3.8+ 3.175 = -0.625

Find the value of x if C is the midpoint of line segment AB, AC=4x+5, and
AB=78?
Answer:
x = 8.5
Step-by-step explanation:
AC + CB = AB
As C is the midpoint AC = CB = 4X + 5
AC + CB = AB
4x + 5 + 4x + 5 = 78
4x + 4x + 5 + 5 = 78 {Combine like terms}
8x + 10 = 78 {Subtract 10 from both sides}
8x = 78 - 10
8x = 68
x = 68/8
x = 8.5

Help me pls I’m failing math I need a good grade on this
Answer:
2 2 /5 = 2.4 = 240 %
Step-by-step explanation:
The number 1 is the same as 1.00 and is the same as 100%.
The number 2, therefore, is the same as 2.00 and the same as 200%
2 /5 can be converted into a decimal by seeing that 2 /5 = 4 /10 . 4 /10 , spoken out loud, is "four tenths" and shows that the decimal is
0.4 . And 0.4 is the same as 40%. Which means that 2 2 /5 = 2.4= 240 %

1 options:
y = 3x - 1
y = -3x
y = 3x + 1
y = 3x
2 options:
y = 3/2x
y = -3/2x + 1
y = -3/2x
y = -2/3x
3 options:
y = -4x
y = 4x
y = -4x -2
y = -2x
Answer:
-3x is the answer I'm pretty sure I think
Answer:
Graph 1. y = 3x + 0 or y = 3x
Graph 2. y = 3/-2x + 0 or y = 3/-2x

In a class of 40 students, 75% returned their permission slips for the field trip. How many students returned their permission slips?
Answer:
30
Step-by-step explanation:
75% can also be written as 3/4. 3/4 can also be written as 30/40, or 30 out of 40, which in this case, means 30 out of 40 kids.
Answer:
30 Students Returned their Permission Slips
Step-by-step explanation:
In a class of 40 students, 75% returned their permission slips for the field trip. How many students returned their permission slips?
75% of 40 is 30, therefore 30 students returned their permission slips. 75% is equivalent to 3/4, or 30/40.
