Answer:
600 boys
800 girls
Step-by-step explanation:
Ratio is 3:4
let total number of boys be x
3/4=x/1400-x
4x=3(1400-x)
4x=4200-3x
7x=4200
x=600
600 boys
1400-600 = 800 girls

You can get this my multiplying the scale factor by the height. In this case you need to use the bottom number to multiply since you are going in reverse.
Answer:
B.
Step-by-step explanation:
- Multiplying both numerator and denominator by (5 - 4i) <em>,</em><em> </em><em>t</em><em>h</em><em>e</em><em> </em><em>c</em><em>o</em><em>n</em><em>j</em><em>u</em><em>g</em><em>a</em><em>t</em><em>e</em><em> </em><em>o</em><em>f</em><em> </em><em>t</em><em>h</em><em>e</em><em> </em><em>d</em><em>e</em><em>n</em><em>o</em><em>m</em><em>i</em><em>n</em><em>a</em><em>t</em><em>o</em><em>r</em><em>,</em><em> </em><em>i</em><em>.</em><em> </em><em>e</em><em>,</em><em> </em><em>(</em><em>5</em><em> </em><em>+</em><em> </em><em>4</em><em>i</em><em>)</em><em>.</em>
- Multiplying (4+4i) and (5-4i) using distributive property
- Using the identity <em>(a+b)(a-b)= a² - b²</em> where 5 will act as a and 4i will act as b
(<em>combining like terms)</em>
distributing the denominator
That is, option B.

Answer:
First Equation answer: r > 2
Second Equation answer: 7 (r+3)
Step-by-step explanation:
First Equation Explanation: Move variable to the left side (2r + 2r + 8 > 16)
See the like terms (4r > 16-8)
Divide both sides by inequality of 4 (4r > 8) 4r----> r > 2
Second Equation Explanation: Factor out 7.
