Make an equation system based on the problem
eg. a is the first number and b is the seond number
An equation for "<span>The sum of two numbers is 53" is
</span>⇒ a + b = 53
An equation for "<span>twice the first number minus three times the second number is 26"
</span>⇒ 2a - 3b = 26
<span>
Solve the equations by elimination and subtitution method
Eliminate a to find the value of b
a + b = 53 (multiplied by 2)
2a - 3b = 26
--------------------------------------
2a + 2b = 106
2a - 3b = 26
------------------- - (substract)
5b = 80
b = 80/5
b = 16
Subtitute the value of b to one of the equations
a + b = 53
a + 16 = 53
a = 53 - 16
a = 37
The numbers are 16 and 37</span>
$80.00 x 0.20 = $16.00
$80.00 - 16.00 = $64.00
the hoodie costed $64.00
you were left with $16 to spare
Since its telling you that x is the number of years and the question is "How much does the cost of milk increase EVERY YEAR" then you can conclude that the cost is increasing by 0.25 each year
Answer:
D. 108.4 mm
Step-by-step explanation:
Since the larger triangle is 4 times of the small triangle...
27.1 x 4 = 108.4 mm
First to find what’s 2x you do 25-11=14, and you know that 7 x 2 =14.
So x= 7.
