Answer:
Step-by-step explanation:
<u>Given</u>
<u>We see J is between H and K, so </u>
- KH = HJ + JK
- 2x + 5 + 3x - 7 = 18
- 5x - 2 = 18
- 5x = 20
- x = 4
Answer:
Andre has more money in his savings account.
Step-by-step explanation:
We need to have equations for both Andre and Elena. Andre starts with $100 in his savings and adds $5 per week. Based on this, Andre's equation will be y = 5x + 100. Elena starts with $10 and adds $20 per week. Based on this, Elena's equation will be y = 20x + 10.
Andre: y = 5x + 100
Elena: y = 20x + 10
We have to figure out who will have more money in their account after 4 weeks. To do that, we plug in 4 into x because x is the number of weeks.
Andre: y = 5(4) + 100
y = 20 + 100
y = 120
Andre has $120 after 4 weeks.
Elena: y = 20(4) + 10
y = 80 + 10
y = 90
Elena has $90 after 4 weeks.
Which is greater? $120 or $90? That's right, its $120. Andre has more money in his savings account. I hope this helps!
To subtract fractions, let's put a generic example.
Be the fractions
(a / b) - (c / d)
With a, b, c and d other than zero.
The subtraction of fractions is given by:
(a / b) - (c / d) = ((a * d) - (c * b)) / (b * d).
If the fractions have the same denominator then the subtraction is
(a / b) - (c / b) = (a-c) / (b)
answer
(a / b) - (c / d) = ((a * d) - (c * b)) / (b * d)
(a / b) - (c / b) = (a-c) / (b)
Answer: 169.2cm
Step-by-step explanation:
From the question, we are informed that three equal-sized cardboard boxes are stacked on top of each other and that each box is 56.4 cm in height.
To get the combined height of the 3 stacked boxes, we multiply 56.4cm by 3. This will be:
= 56.4cm × 3
= 169.2cm
Answer:
85%
Step-by-step explanation:
Monday:
200 x 0.70 = 140
200 - 140 = 60
Tuesday:
400 x ? = 60
400 x 0.85 = 340
400 - 340 = 60
