x - 7y = 19 <em>multiply both sides by 5</em>
5x - 35y = 95
Substitute 5x = -2y - 16:
(-2y - 16) - 35y = 95
(-2y - 35y) - 16 = 95 <em>add 16 to both sides</em>
-37y = 111 <em>divide both sides by (-37)</em>
y = -3
Put the volue of y to the first equation:
x - 7(-3) = 19
x + 21 = 19 <em>subtract 21 from both sides</em>
x = -2
<h3>Answer: x = -2 and y = -3 → (-2, -3)</h3>
The price of a flower bouquet is $2.75 according to the information on the question above. This problem can be solved using two linear equations with two different variables based on the transaction. The first equation is 3x +5y= 25.75 and the second equation is 8x+2y=29 which can be simplified as y=14.5-4x. You can find the x by substituting the "y" variable on the first with the second equation resulting in "x =2.75" which is the price of the flower bouquet<span>.</span>
Answer:
54 sweets altogether
Step-by-step explanation:
Jim: 27
Dan:
David:
3:2:1
The amount is divided by 6
27/3=9
Dan— 9*2=18
David— 9*1=9
18+9+27=54
ANSWER: $4.95
EXPLANATION:
So it’s asking us to find out if $4.95 dollars is more than 5.75% of 78.99.
So we need to find 5,75% of 78.99
To find percentage turn the percent into a decimal.
5.75% become 0.575
Now we have 0.575 x 78.99
That is 45.41925
Move the decimal over again and you get 4.541925
Round to the nearest hundredth to get
$4.54
$4.54 < $4.95
So the answer is &4.95
