Answer:
4 quarters and 14 dimes
Step-by-step explanation:
Let x be quarters and since Jorge has 10 more dimes than quarters you can say x + 10. 25 is the quarters and the 10 is the dimes.
25x + 10(x+10) = 240
25x + 10x + 100 = 240
35x = 140
x = 4
Multiply 4 and 0.25 and you get 1.00. Subtract 1.00 from 2.40 to get 1.40. Divide that by 10 (amount of dime) to get 14.
Let's make W = width, and L = length.
What do we know? We know that P = 40 yards, and L = W + 1.5 .
The formulas for perimeter and area are:
P = 2W+2L
A = W*L
We can set P to 40, and since L = W+1.5, we can substitute that in for L.
40 = 2W + 2 (W+1.5)
40 = 2W + 2W + 3
37 = 4W
W = 37/4
We can plug that into L to find the length.
L = W + 1.5
L = 37/4 + 3/2
L = 43/4
Now, we plug into the area formula!
A = L*W
A = 43/4 * 37/4
A = 1591/16 or 99.43 yd^2
Answer:
10x+10 = 110
Step-by-step explanation:
The two angles are vertical angles and vertical angles are equal
10x+10 = 110
Answer:
C and E
Step-by-step explanation:
The variable "y" has to be by itself so here is the breakdown to that:
-3x + 6y + 5 = - 7
6y + 6 = 3x - 7
6y = 3x - 7 - 6
6y = 3x - 12
6y/6 = 3x/6 - 12/6
y = 1/2 x - 2
Then you would graph -2 --> (0, -2) and use 1/2 to navigate upwards to get your answers.
Answer:
The product rule of exponents
Step-by-step explanation:
An expression is 6xa^3 x 3xa^4
This can be hard to answer but there are three rule. 1st you keep the base which is a. 2nd is add the exponents which are 4 and 3. 3rd is multiply the coefficient which is 6 and 3. and this answer would be 18xa^7.
