Answer: 320 grams
Step-by-step explanation:
Let the mas of the teapot be denoted by a
Let the mass of the cups be denoted by c
The question can be turned into an equation which will be:
a + 4c = 1280 ......... equation i
a + 10c = 2720 ........ equation ii
Subtract equation i from ii
6c = 1440
c = 1440/6
c = 240 grams
The mas of the cup is 240 grams
From equation i
a + 4c = 1280
a + 4(240) = 1280
a + 960 = 1280
a = 1280 - 960
a = 320 grams
The mass of the teapot is 320 grams
Answer:
y>x3+x2
Step-by-step explanation:
it has the greater than sign
54+4(34−12)^2 (is the 2 squared?)
=1990 (if so its 1990)
Answer:
1575
Step-by-step explanation:
First of if B if 2x's c minus 1875 do 1875+3525=5400/2=2700$. Then for A's subtract 1875 by 300 1865-300=1575. The answer is 1575
