Answer:
<h2><em>See explanation.</em></h2>Step-by-step explanation:
<h2>1. Subtraction</h2>a. x - 2 = 10
x = 12
12 - 2 = 10.
b. s - 4 = 6
s = 10
10 - 4 = 6
c. y - 10 = 24
y = 34
34 - 10 = 24
d. t - 3 = 9.
t = 12
12 - 3 = 9
<h2>2. Addition</h2>a. x + 2 = 10
x = 8
8 + 2 = 10
b. s + 4 = 6
s = 2
2 + 4 = 6
c. y + 10 = 24
y = 14
14 + 10 = 24
d. t + 3 = 9
t = 6
6 + 3 = 9
<h2>3. Multiplying Fractions</h2>a. 1/2x = 10
x = 20
1/2(20) = 10
b. 1/4s = 8
s = 32
1/4(32) = 8
c. 1/3t = 6
t = 18
1/3(18) = 6
d. 1/5y = 20
y = 100
1/5(100) = 20
<h2>4. Multiplying Whole Numbers</h2>a. 4x = 32
x = 8
4 * 8 = 32
b. 13x = 39
x = 3
13 * 3 = 39
c. 5x = 25
x = 5
= 5
5 * 5 = 25
d. 10x = 100
x = 10
= 10
10 * 10 = 100.

Answer:
x ≈ 3.1 ft
Step-by-step explanation:
The segment from the centre to the chord is a perpendicular bisector, thus
The triangle is right with base = x
Applying Pythagoras' identity to the right triangle, then
( x )² + 1.4² = 2.1²
x² + 1.96 = 4.41 ( subtract 1.96 from both sides )
x² = 2.45 ( multiply both sides by 4 )
x² = 9.8 ( take the square root of both sides )
x = ≈ 3.1 ft ( to the nearest tenth )
