Suppose that x,y,z are positive integers satisfying x <= y <= z, and such that the product of all three numbers is twice their sum. What is the sum of all possible values of z?
All solutions
1. x = 1 , y = 3 , Z = 8
2. x = 1 , y = 4 , Z = 5
3. x = 2 , y = 2 , Z = 4
The temperature inside a scientific instrument was measured as 37.5 °C. Find the Fahrenheit temperature by multiplying the Celsius temperature by 1.8 and adding 32. *
Answer:
99.5
Step-by-step explanation:
if you have a calculator put in 37.5 * 1.8 hit = then add 32
find the sum 1/2 + 3/8
Answer: 7/8
Step-by-step explanation:
The easiest way to do this is to find a common denominator, so first we find out 2 times how much equals 8? 2x4 = 8. So with 8 being our common denominator, we have to multiple 4 to every number in the fraction 1/2. So 1x4 = (4/8) = 2x4. Then you just add the top numbers, so 4 + 3 = 7 and keep the denominator. 7/8.
Answer:
Step-by-step explanation:
0.5 + 0.375 = 0.875
0.875 = 7/8
I’m running low on brain cells can I get some help and please explain how u got the answer.
Answer:
50
Step-by-step explanation:
line up the numbers based on type of units like this
$1000 represents 100%
$x represents 5%
cross multiply
x*100= 1000*5
divide both sides by 100 to isolate x
x= 1000*5/100= 10*5= 50
If you were babysitting, would you rather
Charge $5 for the first hour and $8 for each additional hour?
Or
Charge $15 for the first hour and $6 for each additional hour?
Explain your reasoning.
Answer:
wouldn't you charge more to get mroe money lol or am i reading this wrong?
Step-by-step explanation:
If i want more money i would pick the 15 dollars and 6 dollars cuz i will get more money..
Answer:
Charge $15 for the first hour and $6 for each additional hour?
Explain your reasoning.
Step-by-step explanation:
Because they could just keep like adding on hours and I'd rather be making 2 dollar's more even though the first hour is 15$. If they just keep adding on hours it could add up and be more beneficial. Im sorry if that didnt make sense its hard to explain. :) ask questions if needed lol
Edit: Idk it depends if your only babysitting for a few hours than obviously the $15 and $6 one.
But if you dont know how long your babysitting for or your babysitting for longer than the first option.

Answer:
The answer is 1/8 pints left
Step-by-step explanation:
If you had 3/4 pints already and you poured 5/8 pints into your glass, you would only have 1/8 pints left. First you need to make them both have the same denominator (8) to do that you need to multiply 3/4(2)=6/8. 6/8-5/8=1/8 pints left.
150% of $22 (math test)
Answer:
$33
Step-by-step explanation:
Since you already have $22 because of the 100 in 150%, you just need to find 50% of $22 and add it to 22.
22 x 0.5 = 11
11 + 22 = $33

What is the point on the graph of f(x) = (2/3) ^ x when x 1 ?
Answer: f(x)= 2(3)^x
putting x = 0
y = f(0) = 2(3)^0= 2
so at x = 0 y should be 2
putting x = 1
y = 2(3)^1 = 6
so at x = 1 y should be 6
select the graph which has these points
so option A is your answer
Step-by-step explanation: idk i got it correct on a quiz

Martha (from problem 9) has some expenses each week. Each week she buys $9.72 worth of
supplies to help her in her business. Assuming she starts with a zero balance, what would the balance be
in her account after three weeks?
if Martha is not earning money to pay it back, it would be negative. Each week, she loses -9.72 dollars. so -9.72 x 3 weeks = your problem. I'll let you take it from there and solve the rest
$1750 x 21 days = $36,750 for her daily article
9.72 x 3 weeks = $29.16
$36,750 - $29.16 = $36,720.84
balance = $36,720.84

You separate bulbs of garlic into two groups: one for planting and one for cooking. The tape diagram represents the ratio of bulbs for planting to bulbs for cooking. You use 6 bulbs for cooking. Each bulb has 8 cloves. How many cloves of garlic will you plant?
Using simple mathematical operations we can tell that we will plant 48 cloves of garlic.
What exactly are mathematical operations?A mathematical "operation" is the process of calculating a value utilizing operands and a math operator. There are predefined rules associated with the math operator's symbol that must be applied to the supplied operands or numbers.The order of operations refers to the rules that govern how to solve an expression with several operations. Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction are all referred to as PEMDAS (from left to right).So, the number of cloves of garlic we can plant:
We know that there are 8 cloves in each bulb.And in the tape diagram, we can see that there are 6 bulbs kept for planting.So, the number of cloves planted will be:
6 × 8 = 48Therefore, using simple mathematical operations we can tell that we will plant 48 cloves of garlic.
