Write 5(6x+4)-2(5x-2) in the form a(bx+c) where a,b and c integers and a>1

Tamiku [17]

Answer:

Step-by-step explanation:

$5(6x+4)-2(5x-2)\qquad\text{use distributive property}\ a(b+c)=ab+ac\\\\=(5)(6x)+(5)(4)+(-2)(5x)+(-2)(-2)\\\\=30x+20-10x+4\qquad\text{combine like terms}\\\\=(30x-10x)+(20+4)\\\\=20x+24$

$20x=4\cdot5x\\\\24=4\cdot6\\\\20x+24=4(5x+6)$

Sue needs to drive 372 miles to visit her aunt. She stopped at a gas station one-third of the way in to her trip. How many miles

IRINA_888 [86]

Answer:

Sue has traveled 124 miles.

Step-by-step explanation:

Here, the distance covered by Sue is a fraction of the total distance to be covered.

The total distance to her aunt's = 372 miles

but the gas station is at one-third of the distance to be covered.

Thus,

Miles traveled by Sue = $\frac{1}{3}$ x 372

= 124

Miles traveled by Sue = 124 miles.

Therefore Sue has traveled 124 miles.

Find the value of the trigonometric ratio, cos L.

Alekssandra [29.7K]

Answer:

b/h

Step-by-step explanation:

remember SOH CAH TOA. Sin = opposite/hypotenuse, cos = adjacent/hypotenuse, tan = opposite/adjacent. So in this case use CAH for cos L. Adjacent to L is b, and the hypotenuse is h. Therefore the answer is b/h.

Anni [7]

Answer:

57 million square miles

Step-by-step explanation:

Let the area of water is w and area of land is l.

<u>Their ratio is:</u>

w/l = 7/3

133 / l = 7/3

Find the value of l

l = 133*3/7
l = 57 million square miles
