Step-by-step explanation:
Multiplying or dividing each part of the ratio gives an equivalent ratio
Given
8 : 20 ← divide both parts by 2
= 4 : 10 ← divide both parts by 2
= 2 : 5 ← ratio in simplest form
Multiply both parts by 2
8 : 20 = 16 : 40
4 : 10, 2 : 5, 16: 40 ← are possible equivalent ratios

Answer:
Step-by-step explanation:
Given
Initial Temperature = -10
Increment = 5
Required
Solving (a): Write an Equation
The equation is to add the initial temperature and the increment
i.e
Equation = Initial Temperature + Increment
Solving (b): Solve the equation
Substitute values for initial temperature and the increment
Result = -10 + 5
Result = -5
Solving (c):
It's a negative answer because the increment in temperature is not greater than the initial temperature

Define jam and bread mix
------------------------------------------------------
Let the number of jar of jam be x
Let the number of packages of bread mix be y
------------------------------------------------------
Form equations and solve
------------------------------------------------------
x + y = 8 --------------------- (1)
6x + 5y = 45 ---------------- (2)
------------------------------------------------------
Rewrite equation to make x the subject
------------------------------------------------------
x+ y = 8
x = 8 - y ----------------------------(1a)
------------------------------------------------------
Substitute (1a) into (2)
------------------------------------------------------
6(8 - y) + 5y = 45
48 - 6y + 5y = 45
y = 48 - 45
y = 3
------------------------------------------------------
Substitute y = 3 into (1) to find x
------------------------------------------------------
x + 3 = 8
x = 8 - 3
x = 5
------------------------------------------------------
Find jam and bread mix
------------------------------------------------------
Jars of Jam = x = 5
Packages of bread mix = y = 3
------------------------------------------------------
Answer: Jam = 5 ; bread mix = 3
------------------------------------------------------
