The larger of two numbers is 15 more than three times the smaller number. If the sum of the two numbers is 63, find the numbers
Amanda [17]

Answer:

The smaller number equals 12, the larger number equals 51.

Step-by-step explanation:

x + (3x + 15) = 63

Combine like terms.

4x + 15 = 63

Subtract 15 from both sides.

4x + (15 -15) = (63 - 15)

4x = 48

Divide both sides by 4.

4x/4 = 48/4

x = 12

Check answer.

12 + (3(12) + 15) = 63

12 + 36 + 15 = 63

63 = 63

Find the value of x please!! ASAP
cricket20 [7]

Answer:

x = 10

Step-by-step explanation:

By looking at the picture, I can tell the angle of the 3x is also 30 degrees.

This means 3x = 30.

When you solve for x by dividing each side by 3, you result with the answer of x = 10.

To check you work, plug in 10 for x to recieve 30 degrees again.

(2.9X10^5)X(3.4X10^3 in standard form
Evgesh-ka [11]

By using exponent, it can be verified that

(2.9 \times 10^5) \times (3.4 \times 10^3) in standard form is 9.86 \times 10^8

What are exponent?

Exponent tells us how many times a number is multiplied by itself.

For example : In 2^4 = 2 \times 2 \times 2 \times 2

Here, 2 is multiplied by itself 4 times.

If a^m = a \times a \times a ... \times a (m times), a is the base and m is the index.

The laws of index are

a^{m + n} = a^m \times a^n\\a^{m - n} = \frac{a^m}{a^n}\\(\frac{a}{b})^m = \frac{a^m}{b^m}\\(ab)^m = a^m b^m\\a^0 = 1\\a^{-n} = \frac{1}{a^n}

The given exponent is

(2.9 \times 10^5) \times (3.4 \times 10^3)\\9.86 \times 10^{5+ 3}\\9.86 \times 10^8
