Multiplying with 6 is like multiplying with 3 because, you just double it. Let's say 3 × 4 = 12
Its the same as 6 × 2 = 12 ... which is just 3 + 3 + 3 + 3 . ((:

It has a common multiple.so pretty much *ALMOST* anything you multiply with either of them you can do for the other one

3 x 10=30
~ GOOD
6 x 5=30

3 x 7= 21
~ BAD
6 x 3=18

48 girls, 41 boys, and 5 teachers sat in the gym. Write the ratio of girls to boys in three ways.

Anika [276]

Answer:

Step-by-step explanation:

The answer is D because the question is asking for girls to boys. So anything that has 5 in it is wrong because it isn't asking for teachers, which eliminates A. So since it is asking girls to boys the number order has to be 48 then 41 because it is asking for girls first then to boys. So that makes B wrong. When it comes to the fraction part of the ratio the first number it is asking for (which is girls) always goes on top. So that eliminates C which leaves only answer to be D.

Solve by completing the square x squared +14x - 51=0

Nesterboy [21]

$x^2 +14x - 51=0\\ \\\Delta = b^{2}-4ac =14^{2}-4*1*(-51)=196+204=400 \\ \\x_{1}=\frac{-b-\sqrt{\Delta }}{2a} =\frac{-14- \sqrt{400}}{2}=\frac{-14-20}{2}= \frac{-34}{2}=-17\\ \\x_{2}=\frac{-b+\sqrt{\Delta }}{2a} =\frac{-14+ \sqrt{400}}{2}=\frac{-14+20}{2}= \frac{6}{2}=3$

Complete the following proof. Given: m ∠XOY = m ∠WOV m YZ = m ZW Prove: m XZ = m ZV

horsena [70]

Answer:

Step-by-step explanation:

m ∠XOY = m ∠WOV

so, m XY = m WV --- (i)

{ If angle subtended by two arcs at the center are equal, then length of arc are equal}

m YZ = m ZW ------- (ii) {given}

Add (i) and (ii)

XY + YZ = WV + ZW

XZ = ZV

Hence proved.
