Answer:
x=5/4
r =20
Step-by-step explanation:
On the left we have 9x -7
On the right side we have -3x + 8
9x-7 = -3x+8
Add 3x to each side
9x+3x-7 = -3x+3x+8
12x -7 = 8
Add 7 to each side
12x -7+7 = 8+7
12x = 15
Divide each side by 12
12x/12 =15/12
x = 5/4
Carnival T
7+.5r
Carnival Q
12+.25r
Set them equal for the cost to be the same
7+.5r=12+.25r
Subtract .25r from each side
7+.5r-.25r=12+.25r-.25r
7+.25r = 12
Subtract 7 from each side
7-7+.25r = 12-7
.25r = 5
Divide each side by .25
.25r/.25 = 5/.25
r=20

Can 702 be written as the product of two prime numbers?
Answers
Answer:
Since the sum of its digits equals nine, 702 is divisible by nine.
702 is a composite number.
Prime factorization: 702 = 2 x 3 x 3 x 3 x 13, which can be written 702 = 2 x (3^3) x 13
The exponents in the prime factorization are 1, 3, and 1. Adding one to each and multiplying we get (1 + 1)(3 + 1)(1 + 1) = 2 x 4 x 2 = 16. Therefore 702 has exactly 16 factors.
Factors of 702: 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
Factor pairs: 702 = 1 x 702, 2 x 351, 3 x 234, 6 x 117, 9 x 78, 13 x 54, 18 x 39, or 26 x 27
Taking the factor pair with the largest square number factor, we get √702 = (√9)(√78) = 3√78 ≈ 26.49528.

Here are four number cards
9361
a) Using only two of the cards, write down the largest two digit number
that can be made.
b) Using only three of the cards, write down the three digit number closest
to 200 that can be made.
Answers
Answer: a) 96
b) 196
Step-by-step explanation:
So the 4 numbers are 9361
a) the largest two digit number that can be made. Choose the two largest numbers and that is your answer. So the answer will be: 96
b) write down the three digit number closest to 200 that can be made.
So, first look at the numbers you can make. so the number closest to 200 obviously has to start with 1 so the first number is 1. then the second highest number is 9 and the third is 6, thefore the answer is:
196

Fill in the missing work and justification for step 3 when solving 2(x + 1) = 10.
Answers
Answer:
2(x + 1) = 10
x = 4
Step-by-step explanation:
Given:
2(x + 1) = 10
Solution:
Apply Distributive property
A*(B+C) = (A*B) + (A*C)
This means multiply 2 with x and 1
2*(x+1) = (2*x) + (2*1)
2x + 2 = 10
Use Subtraction property of equality
A = B, then A - C = B - C
Subtracting 2 from both sides:
2x + 2 - 2 = 10 - 2
2x = 8 Step 3
Use Division property of equality
It state that if you divide both sides of an equation by same nonzero number then the sides remain equal
Dividing both sides by 2
2x/2 = 8/2
x = 4
This means value of x is 4
Another method to solve this equation is:
2(x+1)=10
Use Distributive property
A*(B+C) = (A*B) + (A*C)
2*(x+1) = (2*x) + (2*1)
2*(x+1) = 2x + 2
Use commutative property
A + (-B) = (-B) + A
2x + 2 + (-2) = 2x + (-2) + 2
2x + 2 + (-2) = 10 + (-2)
2x + 2 - 2 = 10-2
2x = 8
Using division property
AX = B
AX / A = B / A
So
X = B/A
This becomes:
2x = 8
2x = 8.
Divide both sides by 2
2x / 2 = 8 / 2
x = 4

A six-sided dice is rolled twice. What is the probability that a one is rolled both times?
Answers
The probability of rolling a one is 1/6 because there is one side labeled "1" out of 6 sides total.
Assuming the two dice rolls are independent of one another, the probability of rolling two "1"s is (1/6)*(1/6) = 1/36.
There are 36 ways to roll two dice and only 1 way to get snake eyes.
Is y= -2 a function? Someone please help me ✌️✨
Answers
Answer:
no it's not
hope it helps;)
Answer:
No
Step-by-step explanation:
A function is defined as a set of outputs based on a set of inputs.
This means that we need to have two variables in order for this to be a function.
y needs to change as we input different values of x.
However, there are no x values here! It's just a simple line.
Therefore this is not a function.

15 - 4j = 43
Help me
Answers
Answer:
I did not understand your question so this is what I know. If it is correct pls mark me brainliest.
Step-by-step explanation:
15 + -4j = 0
Solving for variable 'j'.
Move all terms containing j to the left, all other terms to the right.
Add '-15' to each side of the equation.
15 + -15 + -4j = 0 + -15
Combine like terms: 15 + -15 = 0
0 + -4j = 0 + -15
-4j = 0 + -15
Combine like terms: 0 + -15 = -15
-4j = -15
Divide each side by '-4'.
j = 3.75
Simplifying
j = 3.75
The solution of the linear equation with single variable 15 - 4j = 43 will be negative 7.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation with a single variable 'j' is given below.
15 - 4j = 43
Simplify the equation, then the value of the variable 'j' will be calculated as,
15 - 4j = 43
-4j = 43 - 15
j = 28 / (-4)
j = - 7
The arrangement of the direct condition with a single variable 15 - 4j = 43 will be negative 7.

„Ms. Karone orders a total of 350 black, blue, and red pens for the school.
• She orders 170 black pens.
• She orders 120 blue pens.
Which equation can be used to find r, the number of red pens Ms. Karone
orders?
350 - 170 – 120 =r
350 + 170 + 120 =
350 – 170 + 120 = r.
350 +170 – 120 = r
Answers
Answer:
350 - 170 – 120 = r
Step-by-step explanation:
Since there is a total of 350 black, blue, and red pens, and we know how many black and blue ones there are, this can be used to find the number of red ones.
350 - 170 – 120 = r can be used to find the number of red pens, because if you subtract the amount of black pens (170) and the amount of blue pens (120) from the total, that will leave you with r, the amount of red pens.
So, 350 - 170 – 120 = r is the correct equation.
