Answer:
Step-by-step explanation:
1) 737/7= 105.285714 so 105 pencils per class and 2 pencils left over
2) 342/3= 114 so 114 people
3) 558*7= 3906 so 3,906 marbles in total
4) 835/5 = 167 children per house
5) 156*12= 1872 so 1,872 apples
6) 138*92= 12696p or 126.96 pounds

Answer:
The ordered pair solution is (-2, 8)
Step-by-step explanation:
y = -4x ------ equation 1
y = 2x + 12 ---- equation 2
We solve for x by substitution;
Substituting the value of y into equation 2;
y = 2x + 12
-4x = 2x + 12
-4x -2x = 12
-6x = 12
Divide by -6
x = 12/(-6)
x = -2
From equation 1;
y = -4x
Substituting the value of x;
y = -4×(-2)
y = 8.
PROOF;
y = -4x
8 = -4*(-2)
8 = 8

Step-by-step explanation:
This is what I got
Answer:
a)$15.95
b) 8kg
Step-by-step explanation:
a)Approach this question by finding how much does it cost for 1g
So,
$2.1/50=$0.042per gram
then, multiple 380 to get the cost of sweets for 380 g
$0.042/gram*380gram=$15.96(Note: the gram cancel out each other)
Which is $15.95 as the question requested
b)This question stated that 3/4 of the metal has 15 kg
So, in order to find the total mass of metal we invert the 3/4 fraction
e.g 4/3*15=20kg
now we have the total mass we can find the mass for 2/5 of the metal
2/5*20kg=8kg
