Carrah has these cans of soup in her kitchen:
2 cans of tomato soup
3 cans of chicken soup
2 cans of cheese soup
2 cans of potato soup
1 can of beef soup
Carrah will randomly choose one can of soup. Then she will put it back and randomly choose another can of soup. What is the probability
that she will choose a can of tomato soup and then a can of cheese soup?
2/10 (or 1/5 ) Times 2/10 (or 1/5).
This will equal a 1 out of 25 chance.
You take the number of items you are looking for ( for example, 2 Tomato Cans) Divided by the total items you have (All 10 cans that are a possibility). Then you take your probabilities, and multiply them.

x+y=8
y=3x
Answer:
x = 2
y = 6
Step-by-step explanation:
x + y = 8
x + (3x) = 8
4x = 8
4x ÷ 4 = 8 ÷ 4
x = 2
-------------------------------
y = 3x
y = 3(2)
y = 6
----------------------------------
x + y = 8
(2) + (6) = 8
8 = 8

Fernando had to pay $1.40 in sales tax when he purchased a shirt . If the sales tax rate is 7% how much did his shirt cost
Answer:
$20
Step-by-step explanation:
Work backwards so Price(.07) = $1.40 so x (.07) = 1.40, solving for x then
x = 1.4/.07 so x = 20
The cost of the shirt of Fernando is $20.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that Fernando had to pay $1.40 in sales tax when he purchased a shirt . The sales tax rate is 7%.
The cost of the shirt is calculated as,
$1.40 = x (.07)
x = 1.4/.07
x = $20
Therefore, the cost of the shirt of Fernando is $20.

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

( — + a ) - ( — • a ) = 0

Simplify —

Solve : -3a+4 = 0
Subtract 4 from both sides of the equation :
-3a = -4
Multiply both sides of the equation by (-1) : 3a = 4
Divide both sides of the equation by 3:
a = 4/3 = 1.333

Answer:
5) First you have to find x, then use it with supplementary angles theorem.
6) STQ = 150˚
Step-by-step explanation:
To find x, add (2x+8), (71-x), and 90˚ together to add up to 180˚ (those three angles are supplementary):
(2x+8) + (71-x) + 90 = 180˚
x + 169 = 180
Then solve for x:
x = 11
You can check if x is right by inputing it back into the two equations and see if all three of the angle measures together equal 180˚.
Now, you only need m∠MTS (2x+8) to find m∠STQ...
m∠MTS + m∠STQ = 180˚ because they are supplementary angles.
Input the found x to find m∠MTS:
(2(11)+8) = 30
Subtract 30 from 180 to find m∠STQ:
180 - 30 = 150
m∠STQ = 150˚
Hope this helped :)
