Split this figure into 3 shapes: 2 triangles and 1 trapezoid

Area of top triangle = 1/2(7)(2) = 7 square units
Area of bottom triangle = 1/2(3)(7) = 10.5 square units
Area of trapezoid = 1/2(3 + 6)(4) = 18 square units

Area of the polygon = 7 + 10.5 + 18 = 35.5 square units

Look at the picture.
A_I=\dfrac{7\cdot2}{2}=7\\\\A_{II}=\dfrac{4\cdot3}{2}=6\\\\A_{III}=\dfrac{7\cdot3}{2}=10.5\\\\A_{IV}=3\cdot4=12\\\\The\ area\ of\ the\ polygon\\\\A=A_I+A_{II}+A_{III}+A_{IV}\\\\A=7+6+10.5+12=35.5\ un^2

Rewrite 5a-(a-3b) in standard form
slamgirl [31]
So, -(a-3b) becomes -1(a-3b). Then, this becomes 5a-1a+3b. There is +3b because there is a double negative. So, 5-1=4, so your answer is 4a+3b. Pls brainliest

Jasper's lawn is 3/4 of an acre in size. The fertilizer bag states that 5 1/2 bags are required for 1 acre. How many bags does J
Nady [450]

Answer: 4\dfrac{1}{8}\ \text{bags}

Step-by-step explanation:

Given

Jasper lawn is three-fourth of an acre

1 acre of land requires 5\frac{1}{2} bags

convert mixed numeral to fraction

\Rightarrow 5\dfrac{1}{2}=\dfrac{11}{2}

\therefore 1\ \text{acre}\equiv\dfrac{11}{2}\ \text{bags}\\\\\Rightarrow \dfrac{3}{4}\ \text{acre}\equiv \dfrac{11}{2}\times \dfrac{3}{4}=\dfrac{33}{8}\ \text{bags}

\Rightarrow \dfrac{33}{8}\ \text{bags}=4\dfrac{1}{8}\ \text{bags}

Jackson picked apples for his family. He picked a total of 8 1/4 pounds. He took 3 3/4 pounds to his aunt and 2 3/8 to his mothe
GalinKa [24]

Answer: 2 1/8 pounds of apples were left to give his grandmother.

Step-by-step explanation:

He picked a total of 8 1/4 pounds. Converting 8 1/4 pounds to improper fraction, it becomes 33/4 pounds.

He took 3 3/4 pounds to his aunt. Converting 3 3/4 pounds to improper fraction, it becomes 15/4 pounds.

He also took 2 3/8 to his mother. Converting 2 3/8 pounds to improper fraction, it becomes 19/8 pounds.

The total number of apples that he gave to his aunt and mother is

15/4 + 19/8 = 49/8 pounds

The number of pounds of apples left to give his grandmother is

33/4 - 49/8 = 17/8 = 2 1/8 pounds
