Answer:
Step-by-step explanation:
During a sale at the market, steaks sold for $2 and watermelons sold for $1.50. Declan spent $10 and bought a total of 6 steaks and watermelons. How many of each did he buy?
Let us represent
Steaks = x
Water melons = y
Our system of equations is given as:
x + y = 6.. Equation 1
x = 6 - y
During a sale at the market, steaks sold for $2 and watermelons sold for $1.50.
$2× x + 1.5 × y = $10
2x + 1.5y = 10... Equation 2
Substitute
2(6 - y) + 1.5y = 10
12 - 2y + 1.5y = 10
12 - 10 = 2y - 1.5y
2 = 0.5y
y = 2/0.5
y = 4
Answer:
V = 4 volt
Step-by-step explanation:
Given: Electrical power (w) P = 0.5 watt and resistance R ( Ω ) R = 32 ohm
Voltage V = ? (volt)
Formula for calculating electrical power is:
P = V² / R => V² = P · R => V ) √P · R = √0.5 · 32 = √16 = 4 volt
V = 4 volt

Answer:
Step-by-step explanation:
<h3>Q1</h3>
<u>The ratios of corresponding sides of similar figures are equal:</u>
- x / 25 = 24 / 15
- x / 25 = 8 / 5
- x = 25*8/5
- x = 40
<h3>Q2</h3>
<u>Short sides are x and 15, long sides are 36 and 24. The ratios are same:</u>
- x / 15 = 36 / 24
- x / 15 = 3/2
- x = 15*3/2
- x = 22.5
Correct choice is C
You would write the equation like this:
24-10n=64+8n
5x-29>-34
5x>-5
x>-1
x<1
2x+31<29
2x<-2
x<-1
x>1
