7x+8y
Step-by-step explanation:
4x-(-8y-3x)
=4x+8y+3x
=7x+8y
Answer:
l=15 m
Step-by-step explanation:
Given that a blueprint of a plot of land has a scale of cm to m.
i.e. if it measures 1 cm in blue print actual dimension is 1 m.
The length of land measures 15 cm on the blueprint.
For 1 cm actual length = 1 m
So for 15 cm actual length = 15 m
So we get
if l represents the length of the actual piece of land,
l=15 m
Answer: <u><em>Diameter = 10cm</em></u>
<u><em>Circumference = 31.4cm</em></u>
<u><em>Area = 78.57cm2</em></u>
Step-by-step explanation: Radius = 5cm
→Diameter = 2×radius
= 2×5 = 10cm
Diameter = 10cm
→ Circumference = 2 ×22/7 × 5
= 220/7
=31.4cm
→ Area = 22/7 × 5 × 5
22/7× 25 = 78.57cm2

Answer:
Step-by-step explanation:
Given that:
Batting average = 0.25 after 160 times at bat;
Batting Average = Number of hits / number of times at bat
0.25 = number of hits / 160
Number of hits = 0.25 * 160 = 40
He want batting average to improve to 0.333 ; if he makes hit the next x times at bat ; number of hits is needed to improve batting average
Hence,
New average = number of hits / number of times at bat
0.333 = (number of hits + x) / (160 + x)
0.333 = (40 + x) / (160 + x)
