That’s easy it’s 18 because the 9x9=18 and there’s a 10s digit
It's a bit hard to do a model on here, but I'll try to represent it. Note that the "a"s are the shaded parts and the "b"s are the non-shaded parts.
a a a
a a a
a a a
b b b
b b b
There are 9/15 shaded.
A. 32 = 3s + 8
minus 8 from both sides
24 = 3s
divide by 3
<em><u>s</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>8</u></em>
B: Q/10 = 6
multiply by 10 on both sides
Q = 6 × 10
<em><u>Q</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>6</u></em><em><u>0</u></em>
C: 2b -1 = 7
add 1 to both sides
2b = 8
divide by 2
<em><u>b</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>4</u></em>
D: d/8 = 2
multiply by 8 on both sides
d = 2 ×8
<em><u>d</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>1</u></em><em><u>6</u></em>
E: 10u + 5 = 45
minus 5 from both sides
10u = 40
divide by 10
<em><u>u</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>4</u></em>
F: j/11 = 7
multiply by 11 on both sides
j = 7 × 11
<em><u>j</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>7</u></em><em><u>7</u></em>
