First, distribute to simplify the equation.
-3*w = -3w
-3*4 = -12
-3w + (-12) = -18
Now, isolate the variable.
-3w + -12 = -18
+12 +12
- 18 + 12 --> -6
-3w = -6
-3w/-3 = -6/-3 >>>>> w = 2
Answer: w = 2
Answer:
<h2>9cm and 5cm </h2>
Step-by-step explanation:
Note: The unit of the width in the question is suppose to be in cm
<em>"with length 18cm and width 10m"====>>></em> <em>"with length 18m and width 10m"</em>
so given that the dimension of the room is
<em>18mx10m </em>
This is a reduction process since we aim to transfer the dimension to paper
we are reducing the dimension by 2
and 1cm---2m
since 2m will represent 1cm
then the dimension will be
9cm and 5cm

Use this calculator to find the unit<span> rate. A rate is a </span>ratio<span> comparing 2 quantities of different kinds of </span>units<span>. A </span>unit<span> rate is a rate with 1 in the denominator. If a rate is given and the quantity in the denominator is not 1, </span>unit<span> rate is calculated by finding an equal </span>ratio<span> such that the denominator is 1.</span>
Answer:
x = ¹⁰⁄₄,⁵⁄₂, or 2.5
Step-by-step explanation:
Given: 13 - 2(2x + 1) = 1
1. Distribute -2 through the parentheses:
⇒ 13 - 2(2x + 1) = 1
⇒ 13 + (-2)(2x) + (-2)(1) = 1
13 - 4x - 2 = 1
2. Combine like terms:
⇒ 13 - 4x - 2 = 1
⟹ 11 - 4x = 1
3. Subtract 11 from both sides:
⇒ 11 - 11 - 4x = 1 - 11
⟹ -4x = -10
4. Divide both sides by -4:
⇒ -4x ÷ -4 = -10 ÷ -4
⟹ x = ¹⁰⁄₄,⁵⁄₂, or 2.5
5. Check your work:
⇒ 13 - 2(2x + 1) = 1
⇒ 13 - 2(2(2.5) + 1) = 1
⇒ 13 - 2(5 + 1) = 1
⇒ 13 - 2(6) = 1
⇒ 13 - 12 = 1
⟹ 1 = 1 ✔
