Answer:
PB=5
Step-by-step explanation:
Since you know that BD=24, you also know that both segments BC and CD have the same value since they're congruent: 12. You also were given the value of PC. Using Pythagorean Theorm, Substitute 12 for a and 13 for c, so the equation would say
12^2+b^2=13^2
Simplify to get
144+b^2=169
Now subtract 144 from 169 and you get 25. That is b^2. All you have to do now is square root 25 to isolate b.
√25=5
So therefore,
b=5
Lines s and t are perpendicular. As you know perpendicular lines, slope is opposite and reciprocal so if slope of line s = 5 then slope of line t = -1/5
Answer:
Brand B
Step-by-step explanation:
Divide to get the answers.
Brand A: 4 bags for $11.92
11.92/4 = 2.98
Brand B: 6 bags for $17.34
17.34/6 = 2.89
Once you are done dividing, the answer that you get will be the individual price per bags.
So, the answer is: Brand B has cheaper price.
Answer:
x=237/7 and y=-199/7
Explanation:
Multiply the second equation by 2, then add the equations together.
(−2x+3y=−153)
2(x+2y=−23)
Becomes:
−2x+3y=−153
2x+4y=−46
Add these equations to eliminate x:
7y=−199
Then solve 7y=−199 for y:
7y=−199
(Divide both sides by 7)
y=−199/7
Now that we've found y let's plug it back in to solve for x.
Write down an original equation:
−2x+3y=−153
Substitute −199/7 for y in−2x+3y=−153:
Add 597/7 to both sides
Divide both sides by -2
