★ Given question↦

What is the value of x in the figure?

★ Given ↦

one angle is of 61
here,two lines intersect in a right angle.
which is 90

★ lets solve ↦

x + 61 = 90
x = 90-61
x = 29

 ★ Hence angle x= 29

Suppose that y varies directly with x and y =10 when x = 20. What is y when x=15

Vanyuwa [196]

y=13.34 when x=15

Step-by-step explanation:

We are given that x varies directly with y i.e y ∝ x

We know that: y ∝ x then

y= k/x

where k is constant.

So, if y=10 and x=20 we can find k

$y=\frac{k}{x}\\10=\frac{k}{20}\\ k=10*20\\k=200$

Now, we need to find y when x=15

We know that k = 200,

So, $y=\frac{k}{x}\\y=\frac{200}{15}\\y=13.34\\$

So, y=13.34 when x=15

Tissues are sold in packs and boxes A pack holds 20 tissues and a box holds 120 tissues Sia buys P packs of tissues and B boxes

Fynjy0 [20]

Answer:

T=120(P+B)

Step-by-step explanation:

If a pack holds 120 tissues, then P packs will hold (P×120) tissues

This implies,

1 pack : 120 tissues

P packs : 120P tissues

Also, if a box holds 120 tissues, then B boxes will (B×120) tissues

This implies,

1 box : 120 tissues

B boxes : 120B tissues

Writing a formula in terms of T, where T is the total we obtain,

T=120P +120B

Using the idea of factorization we obtain

T=120(P+B)
