Christine crawled:
3 ft* (3/4)= 2.25 ft.
3 ft+ 2.25 ft= 5.25 ft
We already know that 1 ft= 12 in.
5.25 ft* (12in/ 1 ft)= 63 in.
The total distance the two children crawled together is 63 in~
The answer is B. 0.75 because that’s what it would be equal to in decimal form.
Answer:
y = -18
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
<u>Algebra I</u>
- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define systems</u>
y = 5x - 3
3x - 2y = 27
<u>Step 2: Rewrite systems</u>
- Define: 3x - 2y = 27
- Add 2y on both sides: 3x = 2y + 27
- Divide 3 on both sides: x = 2/3y + 9
<u>Step 3: Redefine</u>
y = 5x - 3
x = 2/3y + 9
<u>Step 4: Solve for </u><em><u>y</u></em>
- Substitute in <em>x</em>: y = 5(2/3y + 9) - 3
- Distribute 5: y = 10/3y + 45 - 3
- Combine like terms: y = 10/3y + 42
- Subtract 10/3y on both sides: -7/3y = 42
- Divide -7/3 on both sides: y = -18
The unknown number would be 16.
8 times 2 is 16
<span>The number of fire-extinguisher that are required to be carried onboard motorized boats depends on the size of the boat. The main purpose of fire extinguishers is for the protection of the motor engine. Thus, For a 26 and 40 feet in length, at-least two B-I extinguishers or one B-II are required to carry.</span>
