Answer:
90
Step-by-step explanation:
Since we're starting with a negative we're going to disregard the negative sign and add the numbers together: $10.28 + $39.89 = $50.17. :)
Answer:
152 sq. ft
Step-by-step explanation:
to determine the square you multiply the length by the width (16 by 8)
to determine to area of the triangle you must subtract 12 by 16 in order to get the length of the triangle. then multiply the length (4) of the triangle by the height of the triangle (6)
finally add the areas of the triangle and square together to get the total length of the whole thing.
Answer:
Step-by-step explanation:
Let the larger number = x
Smaller number = y
6x + 7y = 114 ------------(I)
10x - 9y = 66 ------------(II)
Multiply equation (I) by 9 and multiply the equation (II) by 7. After that add the two equations. So that, y will be eliminated and we can find the value of x
(1)*9 54x + 63y = 1026
(II)*7 <u>70x - 63y = 462</u> {Now add}
124x = 1488 {Divide both sides by 124}
x = 1488/124
x = 12
Plugin x = 12 in any of the equation. Here, We are substituting in equation (I)
6*12 + 7y = 114
72 + 7y =114
7y = 114 - 72
7y = 42
y = 42/7
y = 6
The numbers are 12 , 6
The answer is 0.08.
The word "is" in mathematics is another word for "equal to".
The word "of" in mathematics is another word for multiplication.
Let's keep the answer as x.
0.008 = 1/10 * x
1/10x = 0.008
x = 0.08
