Answer:
A and D
Step-by-step explanation:
The coffee shop used 52 pounds of Type A coffee.
Step-by-step explanation:
Cost of Type A coffee per pound = 5.25
Cost of Type B coffee per pound = 4.10
Total pounds used in blend = 142
Total cost = 642.00
Let,
x be the pounds of Type A coffee used
y be the pounds of Type B coffee used
According to given statement;
x+y=142 Eqn 1
5.25x+4.10y=642.00 Eqn 2
Multiplying Eqn 1 by 4.10

Subtracting Eqn 3 from Eqn 2

Dividing both sides by 1.15

The coffee shop used 52 pounds of Type A coffee.

Answer: X>7
Step-by-step explanation:
5x>35
Divide both by 5
5x/5=x
35/5=7
<span>The total weights must add upto 50 lbs. Let x represents the number of 3 lb weights and y represents the number of 10 lb weights, we frame an equation as 3x + 10 y =50. Because there are some 10 lb weight and some 3 lb weights but we dont know the exact number.</span>
Answer: 2 states
Step-by-step explanation:
Every year for 8 years, the Williams family visited 6 different states on vacation. This means for 8 years, the family have visited:
= 8 × 6
= 48 states
Since there are 50 states in total, that means we will subtract 48 from 50. This equals :
50 - 48 = 2 states.
They've 2 states left to visit
