Answer:
9
Step-by-step explanation:
m = j^2 -7p
18 = j^2 -7(9)
18 = j^2 - 63
81 = j^2
√81 = √j^2
9 = j

Step-by-step explanation:
The perimeter of a rectangular tray is 28 inches. The length of the tray is 2 inches longer the width of the tray. Determine the dimensions of the rectangular tray.
Answer:
width = 6 and length = 8
Step-by-step explanation:
perimeter = 2*(length + width). (1)
and we have that length = 2 + width
in (1)
28 = 2 *(width + 2 + width)
14= 2*width +2
width =6
and so length will be 8
PLEASEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE HELP DECIMAL WORD PROBLEM INTO EQUATION
Answer:
136 miles
Step-by-step explanation:
Write an equation to represent the cost of the rental, and then solve the equation to find the number of miles.
Let x = number of miles.
The total cost is the cost per mile plus the base fee.
1 mile costs $0.90
2 miles cost $0.90 * 2
x miles cost $0.90 * x, or simply 0.9x
The base fee is $16.95, so the total to rent for x miles is 0.9x + 16.95
The equation
c = 0.9x + 16.95
gives you the cost, c, for a rental of x miles.
We are told the total cost was $139.35. Replace c with 139.35, and solve for x, the number of miles.
139.35 = 0.9x + 16.95
Switch sides.
0.9x + 16.95 = 139.35
Subtract 16.95 from both sides.
0.9x = 122.4
Divide both sides by 0.9
x = 122.4/0.9
x = 136
Answer: 136 miles

how many is 8x8x8x8x8
The value of the expression "8 × 8 × 8 × 8 × 8" is 32,768, obtained by repeatedly multiplying 8 by itself five times.
The expression "8 × 8 × 8 × 8 × 8" represents the multiplication of the number "8" by itself 5-times. When you multiply 8 by 8, you get 64. Multiplying 64 by 8 gives you 512, and multiplying 512 by 8 yields 4,096. Finally, multiplying 4,096 by 8 results in 32,768.
Therefore, the required value of expression "8 × 8 × 8 × 8 × 8" is 32,768. This indicates that by repeatedly multiplying 8 by itself, a total of five times, we arrive at the final product of 32,768.

if 5t=5 then t is what number
Answer:
1
Step-by-step explanation:
5t = 5
divide equation by 5 to get rid of it
t = 1
This is because 5t means "5 times t". The t is a placeholder for a number.
To solve for t, we divide both sides by 5
5t = 5
5t/5 = 5/5
t = 1
Note how 5t = 5 becomes 5*1 = 5 after replacing t with 1. Because 5*1 = 5 is a true statement, this helps confirm we have the correct answer.
use the benchmark 1/2 to compare 5/8 and 2/7
Answer:
Step-by-step explanation:
if you used a compound statement, it would look like this.
2/7 < 1/2 < 5/8
One half is bigger than 2/7. It is much closer to 1/4 than 1/2. 1/4 = 2/8 so 2/7 is just a little bit less than that.
On the other hand 1/2 is just smaller than 5/8. 1/2 = 4/8 so you can see that 1/2 is less than 5/8.

please help find the sum of all even integers from 2 to 100
Answer:
2550
Step-by-step explanation:
2 + 4 + 6 + ……… + 98 + 100
= (2×1) +(2×2) + (2×3) + ……… + (2×50)
= 2 × (1 + 2 + 3 + ………. + 50)
The sum (S) of n natural numbers is given by -
S = (n × (n + 1) )/2
Therefore,
2 × (1 + 2 + 3 + ……… + 50)
= 2 × ((50 × 51)/2)
= 2 × (2550/2)
= 2 × 1275
= 2550

What is the graph of the linear inequality y≤−3x+4?
Answer:
It would look like the picture I attached at the bottom.
Step-by-step explanation:
We know that the slope is -3 and the y intercept is (0,4) (plugging in 0 for x will get you that point), and then you can just graph an equation like you normally would, using rise/run to go down 3 units for every one unit you go right, and plugging in easy x values to check your work.
It gets a little tricky because the question then adds the inequality, and we see that y is now less than or equal to the original equation.
Since it is less than, we can shade all the values below the graph.
(Also, you should probably note for future reference that if it was just less than, the shading would look the same while the graph itself would be dotted because the values on the line are nor included in the solution set).
Desmos is a great website to use if you're having trouble graphing in the future :)

Answer:2x+5 x would be the number of miles driven
Step-by-step explanation:$305. Plug in 150 for x, and the equation is 2*150+5=x, x being your answer that you are looking for. Do the Order of Operations, which is PEMDAS (Parenthesis, Exponents, Multiplication and Division from left to right, Addition and Subtraction from left to right.) So in other words, do 2*150 first, and you get 300. Now your equation is 300+5=x. Add 300+5, and you get 305=x. So your answer is $305.
