Answer:

y=\frac{47}{14}

Step-by-step explanation:

Given

-10\left(-\frac{1}{2}\right)+\left(-\frac{7}{2}\right)+7y=25

Required

Solve for y

-10\left(-\frac{1}{2}\right)+\left(-\frac{7}{2}\right)+7y=25

Open brackets

\frac{10}{2}-\frac{7}{2}+7y=25

Collect Like Terms

7y=25 -\frac{10}{2}+\frac{7}{2}

Take L.C.M

7y=\frac{50-10+7}{2}

7y=\frac{47}{2}

Divide both sides by 7

y=\frac{47}{2*7}

y=\frac{47}{14}

a) This part is already complete I think..

b) This is a cuboid and lateral surface area of cuboid is: 2(lb +bh + hl)

= 2( 10 × 3 + 3 × 7 + 7 × 10)

= 2(30 + 21 + 70)

= 2 × 121 = 242 cm²

Now, the area of top & bottom: lb

= 2 × 10 × 3

= 60 cm²

Neglecting the top & bottom surface area of cuboid:

= 242 - 60

= 180 cm²

c) The total surface area us 242.. I have already done that part above...

Solve for y:<br> x + 2y = -8<br><br> y=-1/2x+4<br> y=-1/2x-4<br> y=-2x - 4<br> y=1/2x-4
adelina 88 [10]

Answer:

x + 2y = -8 = y = -4 - 1/2x

y= -1/2x + 4 =  y = 4

y= -1/2x - 4 = y = -4

y=-2x - 4 = y = -4

y=1/2x-4 = y = -4

Step-by-step explanation:

(x + 2y = -8 = y = -4 - 1/2x)

x+2y=-8\\2y=-8-x\\y=-4-\frac{1}{2}x\\
