Answer: See explanation.
Step-by-step explanation:
Let's assume that you have a System of two equations. You can solve this System using the Substitution Method.
In order to use that method to solve the System of equations, you can follow the steps shown below:
Step 1: You must choose one of the equations of the system and solve for one of the variables. Let's call this new equation "Equation A"
Step 2: Then you must substitute"Equation A" into the other equation.
Step 3: Now you must solve for the other variable in order to find its value.
Step 4: Finally, you need to substitute the value of the variable obtained in the previous step, into the "Equation A" and then evaluate in order to find the value of the other varibale.
(Note: You can also substitute the value of the variable calculated in Step 3 into any original equation and solve for the other variable to find its value).
Answer:
The algebraic expression is "y - 7".
Step-by-step explanation:
"7 less" means "- 7", so you're subtracting 7 from y. You then write it as "y - 7".
Answer:
Decimal: 0.23
Fraction: 23/100
Percent: 23%
Step-by-step explanation:
In this case, one whole is 100. This is because there are 100 little squares in the one big square.
The amount of shaded squares is 23.
This can be represented as the fraction 23/100. 23/100 is the same as 23 being divided by 100. 23 divided by 100 is 0.23 (our decimal). To find a percent, move the decimal point to the right 2 times. Our percent is 23%.
Answer:
hello : 5/8; 65/100 ; 2/3 ; 7/10
Step-by-step explanation:
lcm: (least common divisor) for : 3 ; 10 ; 8 ; 100 is 600
2/3 = (2×200)/(3×200) = 400 /600
7/10 = (7×60)/(10×60) = 420 /600
5/8 = (5×75)/(8×75) = 375 /600
65/100 = (65×6)/(100×6) = 390 /600
the order of these fractions from least to greatest is:
5/8 ; 65/100 ; 2/3 ; 7/10
Answer:
Step-by-step explanation:
She finished at 1:15 because 15 is 1/4 of 60 minutes in an hour.
