Answer:

(x-3) (x-8)≤150

Step-by-step explanation:

Let the age of Holly be represented as 'x',then

the age of Sue will be: x-3 and the age of jeremy will be x-8,

The product of Sue's age and jeremy's age is atmost 150 then,

(x-3) (x-8)≤150

This inequality can be used to find the age of each sibling.

Three percent of Jennie’s skin cells were burned when she escaped from a fire. If 3.7×10’(of her skin cells were burned then, ho
lora16 [44]

Answer:

The quantity of Jennie's skin cell were not burned is 119.601 × 10^{10}  .

Step-by-step explanation:

Given as :

The percentage of Jennie's skin cell were burned = 3 %

The quantity of Jennie's skin cell were burned = 3.7 × 10^{10}

Let The quantity of Jennie's skin cell were not burned = x

Let Total quantity of whole skin cell = n

<u>Now, According to question</u>

The quantity of Jennie's skin cell were burned = Total quantity of whole skin cell × percentage of Jennie's skin cell were burned

i.e 3.7 × 10^{10} = n × 3 %

Or, 3.7 × 10^{10} = n × \dfrac{3}{100}

Or, n =  3.7 × 10^{10} × \dfrac{100}{3}

Or, n = \frac{3.7\times 10^{12}}{3}

i.e n = 1.233 × 10^{12}

Or, Total quantity of whole skin cell = n = 1.233 × 10^{12}

<u>Now, Again</u>

∵ percentage of Jennie's skin cell were burned = 3 %

So, percentage of Jennie's skin cell were not burned = 100 % - 3 % = 97 %

so , The quantity of Jennie's skin cell were not burned = 97 % of Total quantity of whole skin cell

Or, x = \frac{97}{100} × n

Or, x =  \frac{97}{100} × 1.233 × 10^{12}

∴ x = 119.601 × 10^{10}

So, The quantity of Jennie's skin cell were not burned = x = 119.601 × 10^{10}

Hence,  The quantity of Jennie's skin cell were not burned is 119.601 × 10^{10}  . Answer

What is the value of x when y=10 in the equation y=4x-2
Viefleur [7K]
Substitute y for 10 in the equation and solve using these steps:
10=4x+2
1) Minus 2 from both sides
8=4x
2) Divide both sides by 4 (the coefficient of x)
2=x
The value of x is 2 and we can check this by substituting it back into the original equation, 10 = (4×2)+2.

Which shows the pre-image of triangle X'Y'Z' before the figure was rotated 90° about the origin?
Nadusha1986 [10]

Answer: The last option.

Step-by-step explanation:

1. By definiton, the rotation rule 90° about the origin is:

(x,y)⇒(-y,x)

2. You know that the coordinates of triangle X'Y'Z' are the following:

X'(-2,2)

Y'(0,6)

Z'(1,1)

3. Now, when you apply the rule, you obtain that the coordianates of the pre-image are the following:

X(2,2)

Y(6,0)

Z(1,-1)

Therefore, the answer is the last option.
