Answer:
2a + 10
Step-by-step explanation:
the number = 2(a + 5)
= 2a + 10
Answer:
<u>Clare will need 8 little cubes of 1/2 edge length to build a larger cube that has 4 inches of edge length.</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Little wooden cubes edge length = 1/2 inch
Larger cube edge length = 4 inches.
2. How many little cubes does Clare need to build the larger cube?
We can calculate the number this way:
Number of little cubes for building a larger cube = 4/0.5 (1/2 = 0.5)
Number of little cubes for building a larger cube = 8
<u>Clare will need 8 little cubes of 1/2 edge length to build a larger cube that has 4 inches of edge length.</u>
Answer:
C
Step-by-step explanation:
1,942+835
=2,784
then
2,784/12
=232
NOTE:
/ means divide
I am not so sure that as of now I understand the question
Answer:
X= 50°
Y= 70°
Z= 30°
BDE= 30°
2BDE= 60°
Step-by-step explanation:
(2x -70 )+z+(2x+20)=180...(sum of angle on a straight line)
2x -70 = BDE... alternate angles
Y + (2x-70)+(50+x-20) = 180...(sum of angles in a triangle)
X-20 = z ... alternate and opposite angles
(2x -70 )+z+(2x-+20)=180
2x-70 + x-20 +2x +20= 180
5x -70= 180
5x = 250
X= 50°
X-20 = z
50-20= z
30° = z
2x -70 = BDE
2(50) -70 = BDE
100-70 = BDE
30°= BDE
Y + (2x-70)+(50+x-20)
Y + 100-70 +50 +50 -20 = 180
Y + 200-90=180
Y= 70°
2BDE = 2*30
2BDE= 60°
