A varsity boy's basketball team has ratio of seniors to juniors that is 7:4. If the team is made up of only juniors and seniors,

DENIUS [597]

Answer:

The ratio of seniors to the total team members is 7: 11

Step-by-step explanation:

Let us solve the question

∵ A varsity boy's basketball team has a ratio of seniors to juniors that is 7: 4

∴ seniors: juniors = 7: 4

→ That means seniors have 7 parts and juniors has 4 parts

∴ The seniors' members = 7 parts

∴ The juniors' members = 4 parts

→ Add them to find the total parts of the team

∴ The team's members = 7 + 4 = 11 parts

→ To find the ratio of the seniors' members to the total team's member

divide their parts

∵ The seniors ÷ The total = $\frac{7}{11}$

∵ The seniors' member : The team's members = 7: 11

∴ The ratio of seniors to the total team members is 7: 11

A bag contains purple marbles and red marbles, 34 in total. The number of purple marbles is 2 more than 3 times the number of re

Irina-Kira [14]

Answer:

There are 26 purple marbles in the bag.

Step-by-step explanation:

Firstly, you have to make an expression in terms of x where x represent red marbles. Given that the question says purple marbles is 2 more than 3 times the number of red marbles. So the expression is :

Let red marbles = x,

$purple = 2 + 3x$

$red = x$

Next, given that the total marbles in the bag is 34 so you have to add both marbles together and solve the value of x :

$2 + 3x + x = 34$

$4x = 32$

$x = 32 \div 4$

$x = 8$

Lastly, you have to substitute the value of x into the expression of purple marbles :

Let x = 8,

$purpe = 2 + 3(8)$

$purple = 26$
