Answer:
No.
Step-by-step explanation:
25x + 20y = 5x(5 + 4y)
Distribute the 5x inside the (5 + 4y).
5x * 5 = 25x
5x * 4y = 20xy
25x + 20y ≠ 25 + 20xy, so the two expressions below are not equal.
a ratio is how many X there are per Y. for example, a fraction is a ratio: 10/5 = 2 because there are 2 fives in a ten. but usually a ratio is written as x:y.
so to find these ratios, first we need to find the number of girls. 30 students-16 boys = 14 girls.
the ratio of girls to boys is 14:16 because there are 14 girls to every 16 boys. we simplify this to 7:8.
the ratio of girls to all students is 14:30. we simplify this to 7:15.
the ratio of boys to girls is 16:14, which simplifies to 8:7.
the ratio of boys to all students is 16:30, which simplifies to 8:15.
2x+(-1.5x-2)=4
2x-1.5x-2=4
0.5x-2=4
0.5x=4+2
0.5x=6
x=6×2
x=12
y= -1.5(12)-2
y= -18-2
y= -20
Answer:
the answer will be <em><u>-</u></em><em><u> </u></em><em><u>9</u></em>
Step-by-step explanation:
because <em>4plus</em><em> </em><em>3</em><em> </em><em>is</em><em> </em><em>7</em><em> </em><em>and</em><em> </em><em>minus</em><em> </em><em>one</em><em> </em><em>is</em><em> </em><em>6</em><em> </em><em>and</em><em> </em><em>then</em><em> </em><em>plus</em><em> </em><em>one</em><em> </em><em>is</em><em> </em><em>7</em><em> </em><em>and</em><em> </em><em>then</em><em> </em><em>plus</em><em> </em><em>the</em><em> </em><em>2</em><em> </em><em>and</em><em> </em><em>the</em><em> </em><em>ans</em><em> </em><em>will</em><em> </em><em>be</em><em> </em><em>x</em><em> </em><em>=</em><em> </em><em>-</em><em>9</em>
