4(4 - 3x) = 4 <em>divide both sides by 4</em>
4 - 3x = 1 <em>subtract 4 from both sides</em>
-3x = -3 <em>divide both sides by (-3)</em>
<h3>x = 1</h3>
Answer:
0.02 seconds
Step-by-step explanation: A 70kg man jumps 1.00 meters down onto a concrete walkway. His downward motion stops in 0.02 seconds.
Answer:
36
Step-by-step explanation:
when solving for two variables, we need to find one variable in terms of the other.
so, we can turn:
x - y = 5
into
x - y = 5
+ y + y
x = y + 5
Then, we can substitute "x" in the given equation with "y + 5"
x² - y² = 30
(y+5)² - y² = 30
(y + 5)(y + 5)
F: y² O: +5y I: +5y L: 25 {foil}
y² + 10y + 25 - y² = 30 {cancel y² - y²}
10y + 25 = 30
-25 -25
10y = 5
÷10 ÷10
y = 0.5
x = y + 5
x = 0.5 + 5
x = 5.5
check:
(5.5)² - (0.5)²
30.25 - 0.25 = 30
30 = 30
(TRUE)
now, we must find the value of:
(5.5 + 0.5)²
= (6)²
= 36
So, the value of (x + y)² is found to be 36
hope this helps!!
Answer:
Step-by-step explanation:
7). Ratio of the students who name hockey as their favorite sport to hose who name basketball.
Ratio = 
= 
= 1 : 5
Option W is the answer.
8). Ratio of the students whose favorite sport is either baseball or soccer to the total students,
Ratio = 
= 
= 
= 11 : 19
Option O is the answer.
9). Ratio of the students who prefer soccer, basketball, baseball or hockey to those who preferred another sport,
Students who prefer soccer, basketball, baseball or hockey = 8 + 5 + 3 + 1 = 17
Students who prefer another sport = 2
Ratio = 17 : 2
Option K is the answer.
10). Ratio of total number of students to the students who preferred a sport with round ball,
Ratio = 
= 2 : 17
