80 because if you multiply all them you would get 64,000 then divide it
7:6
reverse the numbers when given a ratio similar to this one. 6x7=42 and 7x6=42 so x is 6 y is 7
Answer:
b. Multiplying decimals less than one is finding a part of a part.
Step-by-step explanation:
A part of a given number implies a selected part of a given number which can be expressed as a fraction of the number. Example, the half of any number is
.
The product of a part and another part can be expressed as;
x
= 
or,
x
= 
or,
x
=
= 
The three examples shows: a part x a part.
Therefore, it would be observed that multiplying decimals less than one is the same as finding a part of a part.
Sagot:
100 cm
Hakbang-hakbang na paliwanag:
Kung ganoon :
Distansya na sakop ng Ruben = 900 centimetri
Distansya na sakop ng Jamie = 10 metro
Pagko-convert sa centimeter:
100 cm = 1 m
x cm = 10 m
Paggamit ng multiplikasyon ng krus:
x = 100 * 10
x = 1000 cm.
Dahil dito Distansya ni Jamie = 1000 cm
Distansya sa pagitan ng Jamie at Ruben;
1000 cm - 900 cm = 100 cm
Answer:
x = 8
Step-by-step explanation:
We solve the equation:
4x + 6 = 38
4x = 38 - 6
4x = 32
x = 32 ÷ 4
x = 8
