Answer:
26. A
27. A
Explanation:
Answer:
y=2/3x +b
-3=2/3(1)+b
b=-11/3
y=2/3x+(11/3)
y=2/3x-11/3
Step-by-step explanation:
Given the slope and one point on the line we use the formula above.
Answer:
.35 x + .70 (20) = .45(x+20)
50=x
Step-by-step explanation:
Let x = liters of 35% salt solution
We have 20 liters of 70%
We have a total of 20+x liters of 45%
.35 x + .70 (20) = .45(x+20)
Distribute
.35x + 14 = .45x +9
Subtract .35x from each side
14 = .10x +9
Subtract 9 from each side
5 = .10x
Divide each side by .1
5/.1 = x
50=x
Answer:
X=35°
Step-by-step explanation:
Opposite angles x=35°
The lengths of the three pencils form a right-triangle, and the two-step problem is:
- 6^2 + 8^2 = 10^2
- 100 = 100
<h3>How to write the two-step problem</h3>
The lengths of the pencils are given as:
6cm, 8cm and 10cm
Using the Pythagoras theorem, we have:
6^2 + 8^2 = 10^2
Evaluate the exponents
100 = 100
Hence, the lengths of the three pencils form a right-triangle
