Answer:
x + y = 36.....Equation 1
x = 7 + 2y...... Equation 2
Step-by-step explanation:
Let the number of:
Orange goldfish = x
Black gold fish = y
Anna has a total of 36 goldfish in her aquarium, some are orange and some are black.
x + y = 36.....Equation 1
The number of orange goldfish is 7 more than twice the number of black goldfish.
x = 7 + 2y...... Equation 2
We can rewrite this as:
x - 2y = 7..... Equation 2
The system of equations below that can be used to describe the number of black and orange goldfish in Anna's aquarium is :
x + y = 36.....Equation 1
x = 7 + 2y...... Equation 2
Y=2x-4
X=2
X+2y=10
X+2x0=10
X+0=10 therefore, x=10
Answer:
$2768.83
Step-by-step explanation:
(22+22+32+32)x 4= 432 in
(92+92+48)x 2=464 in
464+432= 898
898/12= 74.8
74.8 x 37= $2768.83
i feel this may be wrong, but this is what i got
Answer:
28^2 14^2 = 72 w
98 +90 = 188
180-188 = -8 degrees
Step-by-step explanation:
81 = 37.5% of x.
81 = (37.5/100)*x
81 = 0.375x
0.375x = 81
x = 81/0.375
x = 216
The number is 216.
