The table shows the height of Sonya‘s siblings who is taller Frida or Julia compare their hearts using the simple >

Vladimir [108]

Answer:

The height of Julio greater than the height of Frieda .

Step-by-step explanation:

Given height as :

The height of Frieda = 5 $\frac{1}{4}$ ft

The height of Julio = 5 $\frac{5}{6}$ ft

So, The height of Frieda = 5 $\frac{1}{4}$

= 5 + $\frac{1}{4}$

= $\frac{20+1}{4}$

= $\frac{21}{4}$ feet

∴ The height of Frieda = 5.25 feet

And The height of Julio = 5 $\frac{5}{6}$ ft

So, The height of Julio = 5 $\frac{5}{6}$

= 5 + $\frac{5}{6}$

= $\frac{30+5}{6}$

= $\frac{35}{6}$ feet

∴ The height of Julio = 5.83 feet

Since 5.83 feet $>$ 5.25 feet

So the height of Julio $>$ the height of Frieda

Hence The height of Julio greater than the height of Frieda . Answer

Chester, the dog, loves to eat treats. He has eaten twice as many today as yesterday. He has eaten a total of 15 dog treats in b

stich3 [128]

Answer:

The equations are:

$T = 2Y$ and $T + 2Y = 15$

Step-by-step explanation:

Given

Represent bones eaten Today with T and yesterday with Y

Required

Write the equation

In the first statement, we have that:

$T = 2Y$

Reading further; In the second statement

$T + 2Y = 15$

Hence, the equations are:

$T = 2Y$ and $T + 2Y = 15$

Solving further:

Substitute 2Y for T in the second equation

$2Y + 2Y = 15$

$4Y = 15$

Divide both sides by 4

$Y = \frac{15}{4}$

$Y = 3.75$

Recall that

$T = 2Y$

$T= 2 * 3.75$

$T= 7.5$
