1,387 because you just add all the bricks (421+623+343)
Answer:
35 grams
Step-by-step explanation:
The ratio of zinc to copper is 3 to 11
A jar of chemical contains 385 grams if copper
Therefore the number of grams of zinc it contains can be calculated as follows
3/11= x/385
11x= 385
x= 385/11
= 35 grams
Hence the chemical contains 35 grams of zinc
(0,a)
it didnt move left or right on the x-axis
it went up a units (since its half of 2a)
Answer:
ABC = 65
Step-by-step explanation:
The sum of the angles of a quadrilateral are 360
2x-15 + x + 2x-15 +x = 360
Combine like terms
6x -30 = 360
Add 30 to each side
6x -30 +30 = 360+30
6x= 390
Divide by 6
6x/6 = 390/6
x=65
We want angle ABC
ABC = x
ABC = 65
