Mathematics
2 answers:
Natalija [7]3 years ago

Answer:

d = 3 1/4 or 3.25

Step-by-step explanation:

2 + d = 2 - 3 (d - 5) -2

Distribute

2+d = 2 -3d+15 -2

Combine like terms

2 +d = -3d+15

Add 3d to each side

2+d+3d = 15

2+4d = 15

Subtract 2 from each side

2+4d-2 = 15-2

4d = 13

Divide by 4

4d/4 = 13/4

d = 12/4 + 1/4

d = 3 1/4

d = 3.25

Five cats each ate 1/4 cup of canned food . How much food did they eat altogether?
Sauron [17]

We have FIVE cats that each ate 1/4 cup of canned food.

Then, the five of them together ate:

5 times 1/4 cup This in mathematical expression is a profduct of an integer value (5) times the fraction (1/4) which we know how to multiply based on the problems we solved a few minutes ago:

5 * 1/4 = 5/1 * 1/4 = (5 * 1) / (1 * 4) = 5/4 cups

This answer can also be written as a MIXED number given that 5/4 is an IMPROPER fraction (a fraction with numerator larger than the denominator)

5/4 = 1 1/4

Not sure what answer your teacher would prefer. It depends on whether he/she wants you to use fractions or mixed numbers.

Lemon drops and jelly beans are mixed to make a 100 pound mix. if the lemon drops cost $1.90 per pound and jelly beans cost $1.2
vladimir1956 [14]

L = lemon drops

J = jelly beans

L +J = 100

L=100-J

1.90L + 1.20J=1.48*100

1.90(100-j) +1.20J =148

190-1.90J+1.20J=148

190-0.7J=148

-0.7J=-42

J = 60

L=100-60 = 40


40 pounds of Lemon Drops are needed
